摘要
采用Heck偶联法制备了2种芴-三苯胺共聚物P1和P2。这2种聚合物均易溶于常用的有机溶剂,如二氯甲烷、三氯甲烷、四氢呋喃等。热性能和光学性能研究结果证实,多面齐聚倍半硅氧烷(POSS)的引入能够提高聚合物的热稳定性,而且能够有效抑制聚集,从而使芴-三苯胺共聚物的紫外吸收和荧光发射光谱蓝移。
Two fluorene/triphenylamine copolymers, P1 and P2, were synthesized by Heck merization. They were easily dissolved in common organic solvents such as CH2C12, CHC13 and results of thermal and optical properties indicated that the introduction of polyhedral oligomeric coupling poly- THF etc. The silsesquioxanes （POSS） resulted in improved thermal stability and blue shifts in UV absorption and PL emission spectra by significantly suppressing the aggregation of the copolymer backbones.
