聚苯胺衍生物的金属配合物催化法合成及紫外一可见吸收光谱研究

本文以N，N’-二氯醌亚二胺两种衍生物为主单体，通过金属配合物催化法合成的含富电子环和含缺电子环两大类系列共聚物为基础，介绍了该合成方法的优点和影响因素。并对所获得的两个系列共聚物在中性溶剂和酸性溶剂中的紫外可见光谱进行了较详细的探讨，结果表明，在三氟乙酸溶液中缺电子环聚合物与主单体之间的电荷移动移动比富电子环共聚物明显，因此最大吸收波长较大程度的红移。两种主单体中苯环未取代的单体所组成的共聚物因为空间阻力小，紫外可见吸收光谱红移程度较大。

Study On UV-vis Spectra of the Two Series of Copolymers in Neutral Solvents and Acidic Solvents

In this paper, two kinds of monomers, N, N-dichioro-dipheno-quinone-diimine and their derivatives were chosen as the main monomers. Two series of copolymers containing electron-rich and electron-deficient ring were synthesized by using metal complex as a catalyst, and the advantages and influential factors of this synthetic method are illustrated. UV-vis spectra of the two series of copolymers in neutral solvents and acidic solvents are being discussed. The results show that the maximum absorption of copolymers composed of electron-deficient and the main monomer ring have been apparently red-shifted during the solution of trifluoroacetic acid, for the chargeable mobility is better than copolymer that is composed of electron-rich and main monomer ring. Compared to another type copolymer, the copolymer of unsubsitituted benzene ring has less steric hindrance and more red shift.
