硅芴-芴共聚物的合成、表征和光电性能

Synthesis and Photoelectric Property of Silafluorene-incorporated Polyfluorenes

合成了硅芴与芴的共聚物。系统研究了该新型共轭聚合物的溶解性、热稳定性、电化学性能、光物理性能和电致发光性能等。研究发现,无规嵌入少量具有高能隙、低LUMO能量的硅芴单元到聚芴主链中可有效调控聚合物的光电性能。

A novel copolymer of fluorene and silafluorene was synthesized and systematical investigations were made on the influence of the incorporated silafluorene upon the solubility, thermostability, electrochemical property, photophysical property, and electroluminescence property of the conjugated copolymer. The study showed that the random incorporation of a small amount of diphenylsilafluorene, which has high bandgap and low-lying LUMO, into the polyfluorene chain significantly modified the optical and electronic properties of the polymer.
