Abstract: A novel conjugated polynitrile thin film, plasma-polymerized 3- quinolinecarbonitrile (PP3QCN) thin film was prepared by plasma polymerization of

3-quinolinecarbonitrile. Fourier transform infrared (FT-IR), Ultraviolet-visible spectroscopy (UV-Vis), and X-ray photoelectron spectroscopy (XPS) studies revealed that extensively conjugated C=N double bonds were formed in the

deposited plasma film and the plasma polymerization of 3-quinolinecarbonitrile took

place mainly through the opening of the bonds of C N functional group under our experimental conditions. Plasma-polymerized 3-quinolinecarbonitrile thin film

shows a blue emission with relatively high photoluminescence (PL) intensity at about 475 nm wavelength. The fabricated devices with PP3QCN as electroluminescent layer sandwiched between Indium Tin Oxides (ITO) and aluminium (Al) were also found to show a blue emission.

Introduction

It has been shown that –conjugated polymer thin films have great potential in optoelectronic applications [1-3]. Development of new –conjugated polymers with high conjugation lengths and degree of inter-chain order are a possible strategy to

attain better materials for light emitting diode (LED) and photodiode applications [4]. Generally, ultrathin polymer films can be formed in two ways: one is the wet process, including the Langmuir-Blodgett method, spin-coating, dip coating and solution casting; the other is the dry process, such as physical vapor deposition and chemical

vapor deposition (CVD). Among these methods, plasma polymerization is gaining recognition as a good technique to obtain dense, uniform and stable thin films [5, 6].

简介

它已被证明,共轭聚合物薄膜具有巨大潜力

光电应用[1-3]。发展新型共轭聚合物

一般来说,超薄聚合物薄膜可以形成两种方式:一种是湿法工艺,

气相沉积(CVD)。在这些方法中,等离子体聚合是获得

承认作为一个很好的技术,以获得致密,均匀,稳定的薄膜[5,6]。

The interesting optical properties of plasma polymerized thin films critically depend

on the conformation of the -conjugated chains in both the ground and the excited states and on the inter-chain orientation. Several recent reports demonstrate that chain structures exert a considerable effect on the nature and radiative properties of excited states in -conjugated polymers [7]. Controllability and reproducibility of the surface composition of plasma deposition thin film are utmost important to achieve superlative performance. Also, it is well known that several plasma reaction parameters like power input, monomer flow rate and substrate temperature influence the structure and the composition of plasma thin films [8, 9]. And it is now recognized that under low discharge power input conditions, a plasma-deposited polymer is created that retains more of the aromatic ring structures of the starting monomer and resembles a more conventional polymer [10-12].

To our knowledge no report has yet been appeared in the literature on the structural and optical behavior of poly(3-quinolinecarbonitrile). In the present work, the technique of plasma polymerization was used in the preparation of plasma- polymerized conjugated poly(3-quinolinecarbonitrile) thin film (see Table 1).

Results and discussion

The FT-IR spectrum of the PP3QCN thin film deposited at 10 W is illustrated in Fig. 1

as curve b. The absorption spectrum of monomer 3QCN is also shown as curve in Figure 1 for comparison. Clearly, there is a very strong absorption band at 2250 cm-1

for monomer 3QCN, which is ascribable to the C N stretching vibration.

为单体3QCN,这是归咎于CN的伸缩振动。

However, this absorption band no longer existed for the plasma PP3QCN thin film. Instead, there appeared a broader and considerably stronger absorption band at 1663 cm-1 for the plasma PP3QCN film, attributed to the conjugated C=N stretching

vibration, which indicated that extensively conjugated C=N double bonds were

formed during the plasma polymerization of 3-quinolinecarbonitrile through the

opening of C N triple bonds. Moreover, it is also clear that the characteristic

absorption bands at 3020 and 3053 cm-1

for the aromatic C-H stretching vibration

have been preserved to a large extent in the PP3QCN thin film. This suggests that most of the aromatic ring structures of starting monomers are preserved for deposition carried out at the power of 10 W, which is also confirmed by the prominent characteristic absorption bands at 1604, 1555, 1501, and 1410 cm-1

of the aromatic

ring backbone stretching vibrations. It has been reported that [13] C-CN bonds are scarcely prone to electron attack, the high stability of C-CN bonds is in favor of

plasma polymerization of nitrile monomers without fragmentation. Yasuda [14] also

observed that the rate of the plasma polymerization for monomers with a C N triple

bond is greater than that for saturated monomers, which suggests that the C N triple

bonds in the monomers are very reactive in the plasma process and are much more

subject to cleavage than those without cyano groups. Thus, the FT-IR results reveal

that the plasma polymerization of 3-quinolinecarbonitrile has proceeded mainly via

the opening of -bond of the C N functional groups under the discharge power of 10

W. 但是,这种吸收带血浆PP3QCN薄膜不再存在。

The UV-vis absorption spectra of PP3QCN thin film and its monomer 3- quinolinecarbonitrile are shown in Fig. 2. It can be seen that the pure 3- quinolinecarbonitrile shows a maximum absorption band at about 235 nm, which can

be attributed to the - * transition of the aromatic 3-quinolinecarbonitrile ring.

In comparison with the monomer absorption band, the maximum absorption

wavelength ( max) of PP3QCN thin film shows an obvious red shift, the maximum ofred shift of more than 20 nm (257 nm vs. 235 nm) is observed. Moreover, the width of

absorption band for PP3QCN thin film was also found to increase obviously as

compared with that of monomer. It is well known that increasing the length of the conjugated -system generally moves the absorption maximum to longer

wavelengths [15]. Appearance of a red shift and wider peak width indicate that a

larger conjugated -system has been formed in PP3QCN thin film during the plasma polymerization of 3-quinolinecarbonitrile. In other words, the plasma polymerization of

3-quinolinecarbonitrile took place mainly through the opening of the bonds of C N functional group at a plasma discharge power of 10 W, which agrees well with the

FT-IR results. 在与单体的吸收峰,最大吸收比较

In order to get the detailed surface stoichiometry of plasma conjugated polynitrile thin

films, the high-resolution C1s spectra of PP3QCN film were evaluated and the corresponding results are shown in Fig. 3. 为了获得详细的表面化学计量的血浆共轭polynitrile薄

电影,高分辨率C1s的PP3QCN薄膜的光谱进行了评估和

相应结果显示在图中。3。The C 1s spectra were analyzed by fitting Gaussian peaks with a 20% Lorentzian

contribution. It has been reported that the full width at half maximum (FWHW) for plasma polymers is expected to be relatively large, about 2 eV due to their irregular molecular structure [16, 17]. Thus, the C 1s spectra for PP3QCN film were curve- fitted using 2 eV as the full width at half maximum (see Table 2). It should be noted

that some fitting peaks significantly overlap due to the small difference in the binding energies associated with these peaks. The C 1s spectra of PP3QCN film can be deconvoluted into five component peaks as indicated in Fig. 3. The binding energy

for aromatic C=N (285.97 eV) and C=C (285.47 eV) was assigned in accordance with

the results in the literature [18] and the peak positions for both aromatic components were fixed during the fit procedure. The other three chemically distinct C atoms are assigned as follows: the peak at 284.90 eV represents saturated hydrocarbon CH; the peak at 286.75 eV represents the C-O group; and the peak at 288.04 eV represents C=O. In addition, a broad high binding energy peak centered at 292.88

eV, which assigned to the - * shake-up satellite arising from the aromatic rings is observed for PP3QCN thin film, indicating that the PP3QCN film contains an extended -electron system. In other words, a higher retention of the aromatic ring structure in the PP3QCN film is obtained during the plasma polymerization of 3- quinolinecarbonitrile. The detailed surface composition of PP3QCN film is shown in

Table 2. The theoretical ratio of the group C=N to C=C in PP3QCN film is 1:2 if plasma polymerization occurred exclusively through the C N triple bond. For the

PP3QCN film deposited at 10 W, this ratio is 1:2.25. 20%的Lorentzian拟合高斯峰的C 1s 光谱进行了分析

To check a possibility of as-grown PP3QCN film as optical device application, photoluminescence (PL) measurements were also carried out and the PL spectrum is shown in Fig. 4. It can be seen from the spectrum that the as-grown plasma PP3QCN thin film show a blue emission with a narrow peak at approximately 475 nm and there appeared a relatively high intensity of PL peak. Clarson et al. [19] reported the preparation and optical property of plasma-polymerized benzene and furan films and found that photoluminescence spectra of these films show a blue emission with a

broad peak at 460 nm for the plasma-polymerized benzene films and 445 nm for the plasma-polymerized furan films, which are different from our results with a narrow emission peak. This discrepancy is probably due to difference in structures of plasma polymer thin films studied. Generally speaking, the optical property of organic materials was influenced by the nature of the lowest electronic excited states. Due to

the strong electron–phonon coupling, the optical property of highly conjugated plasma polymer thin films was influenced by both the ground and excited state equilibrium conformation of the resulting molecules. It has been reported [20] that the emission with a narrow transition and a high PL intensity mainly arises from the crystalline parts. In this research, therefore, the narrow blue emission with a high intensity of PL peak might mainly originate from the crystalline structures formed in conjugated PP3QCN film during plasma polymerization. Indeed, it was found by Boo

[21] through study on the optical behaviors of plasma-polymerized thiophene that there was an existence of some crystalline structures in plasma-polymerized

thiophene films. Furthermore, Since the PP3QCN films were found to show a blue emission, it can be assumed that if these plasma polynitrile films show efficient EL spectra, then they will also be in blue region as that of PL spectra. The EL spectra of

the ITO/PP3QCN/Al devices with different PP3QCN layer thickness are illustrated in Fig. 5 as curves a, b, c, d and e. It is clear that all the EL spectra shapes are similar

to each other and they show a blue emission as its PL spectra. Furthermore, the full width at half maximum (FWHM) for all the EL spectra as a whole is about 95 nm. 要检查作为土生土长的PP3QCN电影光学器件中的应用的可能性,

To develop a new –conjugated polymer thin film for optoelectronic applications, the plasma-polymerized 3-quinolinecarbonitrile thin film was prepared by plasma polymerization technique. FT-IR, UV-Vis, and XPS studies revealed that a higher

retention of the aromatic ring structure in the deposited plasma films is obtained and

the plasma polymerization of 3-quinolinecarbonitrile took place mainly through the opening of the bonds of C N functional group under our experimental conditions. Moreover, the as-grown conjugated polynitrile thin film shows a blue emission with a relatively high PL intensity at about 475 nm wavelength. The conjugated polynitrile thin film obtained from 3-quinolinecarbonitrile precursor might be a promising material

for application in LED and photodiode device.

新视野大学英语1 sectionB文章英译汉翻译

新视野大学英语1sectionB文章翻译 一、While regular schools still exist, the virtual classroom plays an important role in today's learning community.(虽然常规的学校依然存在,但虚拟课堂在今天的教学领域中起着重要的作用。)Job opportunities for students are expanding rapidly and more people of all ages are becoming aware of online learning that allows them to study at home. (随着学生就业机会的迅速增多,越来越多不同年龄层的人开始意识到这种在家就学的网上学习方式。)Online students, however, require unique qualities to be successful.(然而,网络学生需要具备一些特别的素质才能取得成功。)The following list discusses some ideal qualities of successful online students. (以下是网上学生要取得成功必备的一些理想素质。) 1. Be open-minded about sharing life, work, and learning experiences as part of online learning.(与人分享生活、工作及学习经验,这些是网上学习的一部分。) Many people find that the online method requires them to use their experiences and that online learning offers them a place to communicate with each other.(许多人发现网上学习需要他们运用各自的经验,同时又为他们提供了相互交流的场所。)This forum for communication removes the visual barriers that hinder some students from expressing themselves. (这一交流场所消除了一些学生自我表达的视觉障碍。)In addition, students are given time to reflect on the information before replying. (此外,学生在答题之前有时间进行思考,)In this way, students can help to keep the online environment open and friendly.(这就使得网上环境开放而友好。) 2. Be able to communicate through writing. (能通过书写进行交流。) In the virtual classroom nearly all communication is written, so it is critical that students feel comfortable expressing themselves in writing.(虚拟课堂的交流几乎都是书面形式。因而很重要的一点是学生要具有书面表达能力。)Some students have limited writing abilities, which need to be improved before or as part of the online experience. (有些学生书面表达能力差,有待提高,可以在网上学习之前提高或将其作为网上学习的一部分。)This usually requires extra commitment by these students.( 这常常需要他们加倍努力。) Whether working alone or in a group, students share ideas, perspectives and discussions on the subject being studied, and read about those of their classmates. (不管是单独学习还是小组学习,学生们就学习内容交流观点和见解,并展开讨论,同时了解其他同学的意见。)In this way, students gain great insights from their peers, learning from each other as well as the instructor.( 这样,学生可以从同龄人那里得到启发,既跟老师学,又互相学习。) 3. Be willing to "speak up" if problems arise.(说出你的困难。) Remember that instructors cannot see their students in an online course.(记住,虚拟课堂里老师看不见学生。)This means students must be absolutely explicit with their comments and requests.(这就意味学生必须直接明了地表达自己的看法和要求。) If they experience technical difficulties, or problems in understanding something about the course, they MUST speak up; otherwise there is no way anyone can know something is wrong.( 如果碰到技术方面的问题,或在理解课程中遇到困难,必须大胆说出来,否则任何人都无从知晓问题所在。) If one person does not understand something, possibly several others have the same problem.( 如果某人不理解某个问题,或许别人也有同样的问题。) If another student is able to help, he or she probably will.( 如果有哪个学生能解决,他(她)也许就会帮助你。) While explaining something to others, students reinforce their own knowledge about the subject. (学生在给他人解释问题时,自己对该问题的认识也加深了。) 4. Take the program seriously.(认真对待课程。) Online learning is not easier than study in regular classrooms. (网上学习并不比课堂学习容易。)In fact, many students say it requires much more time and effort. (事实上,许多学生说它需要花更多的时间和努力。)Requirements for online courses are no less than those of any other quality program. (网络课程的要求不低于其他任何一种优质课程。)Successful online students, however, see online learning as a convenient way to receive their education—not an easier way. (然而,取得成功的学生认为网上学习是一种便捷的受教育方式,但并不容易。)Many online students sit at computers for hours at a time during evenings and on weekends in order to complete their assignments. (晚上或周末,为了完成作业,许多网络学生在电脑前一坐就是几个小时。)When other people are finished with their work and studies and having fun, you'll most likely find online students doing their course work.(别人已完成作业和学习,开始玩耍,而此时网络学生却很可能还在上课。)Online students need to

5-8单元英语课文翻译

学英语既有乐趣又有回报 文学的研究——包含对哲学、宗教、历史事件的发展和观念由来的研究,不仅是文明的,并且有教化作用,而且是流行的和实际的。在所有从文理学院毕业并获得学士学位的人中,有六分之一的人主修英语。让人惊异的是,这些毕业生能胜任范围相当广泛的工作。他们的经验表明,这种广泛流行的偏见是错误的,即英语专业的学生只能从事新闻或教学工作:事实上,主修英语的学生也为未来从事法律、医学、商业和公职等职业做了相当好的准备。 有人时常劝告期望上法学院或医学院的大学生要学习与他们的择业有直接联系的严格制定的课程。有人还建议未来法学院的学生应该选修政治、历史、会计、商业管理,甚至人体解剖学、婚姻和家庭生活等课程。未来医学院的学生被引导去学习多种理科课程,实际上,这些课程比他们考入医学院所需要的理科课程要多得多。令人惊讶的是,许多法学院和医学院却指出,如此专门化的准备不但没有必要,而且并不可取。没有什么"法律预科”课程:上法学院和从事法律行业的最好的准备是培养学生能够进行批判性的思考;能够进行清晰的合乎逻辑的自我表述;能够对他人的动机、行动和想法进行敏锐的分析。这些技能也正是英语专业要教给学生掌握的技能。 此外,要进入法学院就读,通常需要具有合格院校颁发的学士学位,还需要拿到最低限度的各课平均积分点,并和在法学院录取考试(L.S.A.T.)中取得一个通得过的分数。这项测试包括三个部份:首先是测试阅读理解、图型分类和书面材料评估等能力。测试的第二个部份是考核对英语语法和词汇用法的掌握能力,组织书面材料的能力和文字编辑的能力。第三个部份是检测学生的文学、艺术、音乐、自然科学和社会科学的一般知识。显而易见,主修英语的学生参加法学院录取考试会得心应手。 至于医学院,入学要求主要的一条只是修满32个学时的理科课程。这一要求对主修英语的学生来说肯定不成问题。另外,许多医学院校要求学生必须在医学院入学考试中取得规定的最低分,这一测试对全面发展的文科学生来说又十分有利。医学院入学考试检测四方面的能力:同义词、反义词和词语联想能力;从分数到立体几何学的基本数学知识;文学、哲学、心理学、音乐、艺术和社会科学的常识;以及熟悉中学和大学初始阶段教过的生物学、化学和物理学基本原理的程度。理科基础扎实的主修英语学生完全有能力参加这一考试和医学院入学考试,他们的阅读、分析、阐述和准确交流的能力使他们更胜一筹。学医和行医只会从对人的行为的洞察中受益无穷,而这种洞察却是文学研究才能提供的。 很明显,如此的洞察力对计划以经商为业的学生来说也是很有价值的。这样的学生应该考虑的是,挑选主修对商科有侧重的英语课程是有优势的:这种课程的目的在于在提供文科教育的同时,也为从商职业做准备。对这种教育计划的需求是显而易见的:只有技术性资格的毕业生能找到从商工作,但却经常难以居其位。《华尔街杂志》)和《大学生就业杂志》都有报道,说越来越多的著名商学院的毕业生发现他们自己经常从一种工作或一家公司跳槽到另一个工作或另一家公司,在一个工作岗位上干不了十二个月。雇主们抱怨说,这些表面上年轻有为的男女们根本不会有效地交流,因为他们的文字能力不够强;他们不能够从管理人员培训中学到东西;他们不能够进行有效的口头表达;他们不能用书面形式报告他们的工作进展或问题;他们不能够指导其他工作人员。然而,分析和交流的技能却是管理的最根本的需要。 因此,偏重商业经营管理的主攻英语的学生为未来从事商业管理作好了充分准备。对涉及从银行、保险到通信乃至制造业等众多领域的将近400家公司进行了有关调查,针对是否聘用具有英语学位文凭的毕业生,甚至没有受过行业领域的专门培训的毕业生这一问题,百分之八十五的公司说他们聘用过。拥有英语学位文凭的大学毕业生在营销、系统工程、人事管理、销售、编程、项目设计和劳资关系等领域都工作得十分出色。 主修英语的学生也正在各级政府提供的上千种岗位上工作。就拿可以算得是美国最大的雇主的联邦政府来说吧。从海军陆战队到矿务局,从商业部到国家公园服务处,联邦政府各种机构雇佣的劳动大军近三百万人。主修英语的学生适合做其中的许多工作。最近,向51个联邦政府机构调查了同一个问题:是否聘用有英语学位文凭而却没有受过专门行业训练的大学毕业生,88%的这些联邦政府单位的回答是肯定的。主修英语的毕业生能胜任联邦政府的一系列工作,从索赔审议到外交官到公路安全管理专家等等。再说,那些要求高薪高位的人可能还需要参加一种考试,也就是说,联邦政府每年都要举行"业务和管理职业考试”对大约 10 000种工作岗位的求职者进行考核,而测试的焦点仍然侧重语言技能:理解、分析、阐述、理解概念间逻辑关系的能力,以及解决用文字表述问题的能力。毫不奇怪,主修英语的学生时常在这一考试中获得高分。 简而言之,英语的课程既无局限性又很实用:学习英语是对职业生涯的绝好准备 "日本式英语”能成为一种合法的语言吗? 在我们当地的面包店的招牌上这样写着:"我们希望总能提供给你新鲜的面包并建议你享受有面包吃的生活乐趣,特别是,我们想成为你厨房晚餐的主人。我们用各种不同类型的面包、蛋糕和三明治恭候你们。” 这段话大意清楚,但能认为是正确的英语吗?是的,回答是肯定的,这是一位在日本的美国学者的观点。他说日本式英语与印度英语、牙买加和菲律宾等国说的英语一 样也应看作是合法英语。 教育学博士马歇尔?奇尔兹认为,日本学生应该不管英式 和美式英语的"势利”,以适合自己的方式来说英语,即使这样做 可能会违背语法、发音和句子结构等公认的规则 但是,他对"日本式英语”的推崇却激怒了他的一些同事,而且还在日本的一家英文报纸《读卖新闻》专栏上引发了一场激烈的争论。 奇尔兹先生是日本一所国际学院的院长,他认为两种语言(英语和日语)的混合是可以接受的,因为在日本人听来,这种英文更容易理解。 "创造性地使用语法结构是日本式英语的特征,其结果对那些期待使用标准语法的人来说是非常令人震惊的,但是其意义通常是完全可以理解的,也许这是因为它遵循了自然的思路。 "如果我们(以英语为母语的人)对日本式英语有偏见的话,那是我们的问题,不是日本人的问题。” 作为一个留居日本已有16年之久的居民,奇尔兹先生批评英语语言学校,说它们"羞辱”学生,让他们注册学习"正确的”英语 课。 "我认识一位学生,在学了15 年英语之后,她诚恳地听了一位新老师的意见,从最基础的东西开始,

英语和汉语的区别 一、英语重结构,汉语重语义 我国著名语言学家王力先生曾经说过:“就句子的结构而论,西洋语言是法治的,中国语言是人治的。”(《中国语法理论》,《王力文集》第一卷,第35页,山东教育出版社,1984年) 我们看一看下面的例子: Children will play with dolls equipped with personality chips, computers with inbuilt (成为固定装置的,嵌入墙内的;内在的,固有的)personalities will be regarded as workmates rather than tools, relaxation will be in front of smell television, and digital age will have arrived。 译文:儿童将与装有个性芯片的玩具娃娃玩耍,具有个性内置的计算机将被视为工作伙伴而不是工具,人们将在气味电视前休闲,到这时数字时代就来到了。 这句英语是由四个独立句构成的并列句,前三个句子都用简单将来时,最后一个句子用的是将来完成时,句子之间的关系通过时态、逗号和并列连词and表示得一清二楚。而汉语译文明显就是简单的叙述,至于句子之间的关系完全通过句子的语义表现出来:前三个句子可以看成是并列关系,最后一个句子则表示结果。 二、英语多长句,汉语多短句 由于英语是"法治"的语言,只要结构上没有出现错误,许多意思往往可以放在一个长句中表达;汉语则正好相反,由于是"人治",语义通过字词直接表达,不同的意思往往通过不同的短句表达出来。正是由于这个原因,考研英译汉试题几乎百分之百都是长而复杂的句子,而翻译成中文经常就成了许多短小的句子。 例如:Interest in historical methods had arisen less through external challenge to the validity of history as an intellectual discipline (身心的锻炼,训练;纪律,风纪,命令服从;惩戒,惩罚;学科,科目)and more from internal quarrels among historians themselves. 译文:人们对历史研究方法产生了兴趣,这与其说是因为外部对历史作为一门知识学科的有效性提出了挑战,还不如说是因为历史学家内部发生了争吵。 英文原句是个典型的长句,由27个词组成,中间没有使用任何标点符号,完全靠语法结构使整个句子的意思化零为整:less through...and more from构成一个复杂的状语修饰动词arisen。在中文翻译中,"产生兴趣"这一重要内容通过一个独立的句子表达,两个不同的原因则分别由不同的句子表达,整个句子被化整为零。 三、英语多从句,汉语多分句 英语句子不仅可以在简单句中使用很长的修饰语使句子变长,同时也可以用从句使句子变复杂,而这些从句往往通过从句引导词与主句或其它从句连接,整个句子尽管表面上看错综复杂却是一个整体。汉语本来就喜欢用短句,加上表达结构相对松散,英语句子中的从句
