The objective of the research component of this work is to prepare novel electroactive C2-symmetric or pseudo C2-symmetric molecules and assemble them into helical electroactive macromolecules. The building blocks are bridged triarylamine derivatives. These molecules exist as atropisomers which can be resolved and studied prior to polymerization. The resolved atropisomers are then functionalized with vinyl groups or boronic esters and polymerized using ADMET chemistry or Suzuki couplings. The helical electroactive polymers produced will be characterized by a variety of physical and spectroscopic methods. Minority students in the SPUR program of the Northeast Alliance for Graduate Education will participate in these investigations. An additional educational component of this work is the development of a web based library for the exploration of structures of minerals as well as inorganic and molecular based materials. The site will contain information which should prove useful to students, teachers, and researchers. With this CAREER award, the Organic and Macromolecular Chemistry Program is supporting the research and educational goals of Dr. Dhandapani Venkataraman of the Department of Chemistry at the University of Massachusetts at Amherst. Dr. Venkataraman will explore the synthesis of electroactive materials. These materials are expected to exhibit circularly polarized luminesence. This means they are expected to emit light when they are excited by other wavelengths of radiation. Such materials may be useful for backlighting in liquid crystal displays (LCDs, i.e. computer screens). Students trained as a result of working on this project will gain experience in materials research as well as supramolecular organic chemistry, hence they will have skills needed by both the specialty chemicals and the computer/materials industries. An additional educational component of this work is the development of a web based library for the exploration of structures of minerals as well as inorganic and molecular based materials. The site will contain information which should prove useful to students, teachers, and researchers.

本论文的研究内容是制备新型的C2对称或准C2对称的电活性分子，并将其组装成螺旋状的电活性大分子。 所述结构单元是桥接的三芳基胺衍生物。 这些分子作为阻转异构体存在，其可以在聚合之前被解析和研究。 然后将拆分的阻转异构体用乙烯基或硼酸酯官能化，并使用ADMET化学或Suzuki偶联聚合。 所产生的螺旋电活性聚合物将通过各种物理和光谱方法来表征。 东北研究生教育联盟SPUR项目的少数民族学生将参加这些调查。 这项工作的另一个教育组成部分是开发一个基于网络的图书馆，用于探索矿物结构以及无机和分子材料。该网站将包含对学生、教师和研究人员有用的信息。 有了这个职业奖，有机和高分子化学计划是支持在阿默斯特的马萨诸塞州大学化学系的Dhandapani Venkataraman博士的研究和教育目标。 Venkataraman博士将探索电活性材料的合成。 预期这些材料表现出圆偏振发光。 这意味着当它们被其他波长的辐射激发时，它们会发光。 这种材料可用于液晶显示器（LCD，即计算机屏幕）中的背光。 通过该项目培训的学生将获得材料研究和超分子有机化学方面的经验，因此他们将拥有特种化学品和计算机/材料行业所需的技能。 这项工作的另一个教育组成部分是开发一个基于网络的图书馆，用于探索矿物结构以及无机和分子材料。该网站将包含对学生、教师和研究人员有用的信息。
