摘要： 一些π-共轭高聚物由于具有优良的荧光性能或三阶非线性光学性能而引起了人们极大的兴趣,合成新型可溶性π-共轭高聚物的研究已成为近年来的研究热点.对二乙炔苯的聚合研究已有报道.

关键词: 对二乙炔苯, 聚合, 钴催化剂

Abstract: p-Diethynylbenzene was polymerized in the presence of cobalt-phosphine in diethylamine at room temperature with the yield of ca. 73.0% and the poly(p-diethynylbenzene) was obtained with the molecular weight of 11000. The polymers, being highly soluble in common organic solvents, possess the structure containing π conjugated linear polyenes as the main chain as well as p-ethynylbenzene component as pendant groups and emit intense fluorescence at 451.8 nm excited at UVlight in a toluene solution at room temperature.

Key words: p-Diethynylbenzene, Polymerization, Cobalt catalyst
