聚[2-甲氧基-5-(4-溴-丁氧基)对苯乙炔]新型前聚物的合成及表征

Synthesis and Characterization of New Precursor Polymers of Poly[2 methoxy 5 (4 bromobutoxy)phenylene vinylene]

采用不同方法由三锍盐合成新型的聚电解质前聚物及可溶于有机溶剂的侧链溴代聚对苯乙炔前聚物，发现侧链烷氧取代基上的锍盐并不参与聚合，所得前聚物加热后都可转化为聚对苯乙炔．光物理初步研究表明，溴代侧链聚对苯乙炔与Ｃ６０掺杂后具有良好的光电特性．以ＩＲ、ＵＶ－Ｖｉｓ、１ＨＮＭＲ。

Two kinds of novel water soluble polyeletrolyte and organic soluble precursor polymers of poly(phenylene vinylene) with bromine substituted side chain were synthesized from tri sulfonium salt monomer. The results showed that the sulfonium salt on the butoxy substituted side chain did not take part in the polymerization, thus the organic soluble precursor can be obtained at proper condition. Primarily photo physics studies showed that the poly(phenylene vinylene) with bromine substituted side chain doped with C 60 had good photo electric properties. The structure of the monomer and the precursor polymers were characterized by IR, UV Vis, 1H NMR, GPC and DSC.
