摘要
设计并合成了一种分子主链由共轭链段 - - - 1,4-二苯乙烯基苯 (DSB)与非共轭链段 - - -三缩二乙二醇(TEO)组成的交替型共聚物 (TEO- DSB) ,用多种手段对聚合物的结构进行了表征 .TEO- DSB可溶于氯仿、二氯甲烷等有机溶剂中 ,可以采用旋涂的方法制备成均匀、透明的高质量的薄膜 .TEO- DSB具有优异的耐热稳定性 ,在氮气中的最低分解温度高达 42 0℃ .
An alternating copolymer (TEO-DSB) containing distyrylbenzene (DSB) and tri (ethylene oxide) (TEO) was designed and synthesized. The chemical structure was characterized. Thermal properties were investigated with DSC and TGA under nitrogen atmosphere. The results showed that TEO-DSB has excellent thermal stability and the decomposition temperature is high up to 420 ℃. TEO-DSB is soluble in chloroform and methylene dichloride and the polymer solution can be spin-coated onto various substrates giving highly transparent and homogeneous thin film. This polymer can be used in the fabrication of light-emitting diode.
