CAREER: Helical Electroactive Macromolecules

这项工作的研究部分的目的是制备新型的电活性C2对称或伪C2对称分子，并将它们组装成螺旋电活性大分子。构筑基团是桥联的三芳胺衍生物。这些分子以阿托异构体的形式存在，可以在聚合前进行分解和研究。然后，用乙烯基团或硼酸酯来官能化分解的阿托菲异构体，并使用ADMET化学或铃木偶联进行聚合。生产的螺旋电活性聚合物将通过各种物理和光谱方法进行表征。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，用于探索矿物以及无机和分子材料的结构。该网站将包含对学生、教师和研究人员有用的信息。凭借这一职业奖项，有机和高分子化学项目正在支持马萨诸塞大学阿默斯特分校化学系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。这些材料有望表现出圆偏振发光。这意味着当他们被其他波长的辐射激发时，他们预计会发出光。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，用于探索矿物以及无机和分子材料的结构。该网站将包含对学生、教师和研究人员有用的信息。

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.
