摘要:

本文以EDOT-CH(R)-EDOT为基本模型,向侧链引入噻吩、咔唑、芴等几种典型的光电基团,并通过固相/熔融聚合得到相应的聚合物。详细探讨了聚合物的相关性质和几种典型单体的晶体结构,同时发现烷基链的引入降低了分子间的作用力,使得单体的初始聚合温度(Tonset)降低。

关键词: 聚噻吩衍生物, 固相/熔融聚合, 烷基链影响

Abstract:

New poly(bis-3, 4-ethylenedioxythiophene methine)s derivatives with typical electro-optical moieties of thiophene, carbazole and fluorene as the side chains are obtained by facile solid state polymerization (SSP) or melt state polymerization (MSP). Detail characterizations of these polymers are carried out and some key monomers' crystals are obtained for structures analysis. It is found that existence of alkyl chains decrease monomers onset temperatures for SSP (Tonset) due to the weakening of the intermolecular interaction in crystals.

Key words: Poly (bis-3, 4-ethylenedioxythiophene methine) s derivatives, Solid and melt state polymerization, Alkyl chain effect
