PEHPB 的光电特性

摘要

在温和的反应条件下合成了聚 2-乙炔基 N-己基吡啶.反应是通过直接聚合 2-乙基吡啶和相对应的N-己基卤化物完成的.聚合过程既不需要任何的起始条件也不需要催化剂.聚合反应的聚合物产率很高.聚合物结构是具有 N-己基吡啶分支的共轭结构.测量了聚合物的光电性能.当光电子能量为 2.06 eV时,PEHPB 的光致发光峰出现在 603 nm处.%Poly (2-ethynyl-N-hexylpyridinium bromide) was synthesized under mild reaction condition. This was done by polymerizing 2-ethynylpyridine and the corresponding n-hexyl halides directly. Neither addi-tional initiator nor catalyst was used in the process and the polymerization gave high yield of polymer. The polymer structure has the conjugated polymer backbone system having N-hexylpyridyl moieties. The elec-trochemical properties of the polymer were measured. The photoluminescence peak of PEHPB appeared at 603 nm when the photon energy was 2. 06 eV.
