The synthesis of well-defined luminescent organoboron polymers via a novel three-step procedure starting from silylated polystyrene is reported. Highly selective borylation of poly(4-trimethylsilylstyrene) (PS-Si), followed by replacement of the bromine substituents in poly(4-dibromoborylstyrene) (PS-BBr) with substituted thienyl groups (R = H, 3-hexyl, 5-hexyl), and final introduction of the 8-hydroxyquinolato
报道了从甲硅烷基化聚苯乙烯开始,通过一种新的三步程序合成明确定义的发光有机硼聚合物。聚(4-三甲基甲硅烷基苯乙烯)(PS-Si)的高选择性硼化,然后用取代的噻吩基(R = H、3-己基、5-)替换聚(4-二溴硼基苯乙烯)(PS-BBr)中的溴取代基己基),并最终引入 8-羟基喹啉基部分以 67-83% 的分离产率产生一系列新的有机硼喹啉聚合物。己基取代的聚合物是高度可溶且可溶液加工的薄膜,可在 395 nm 激发时有效地发射 513-514 nm 的光。
