摘要
为克服聚合物电化学发光池 (L ECs)中极性离子传导性聚合物与非极性发光聚合物两相分离的矛盾 ,设计合成了一种聚合物分子主链上同时含有发光链段与离子传导性链段的联二萘功能性发光共聚物 EO- PN.用多种手段对其结构进行了表征 ,并测试了其光致发光性能 .EO- PN的热分解温度高达 390℃ ,可以方便的采用旋涂或熔融的方法成膜 .实验发现 EO- PN是一种紫色发光材料 ,其光致发光最大发射峰位于 395 nm.
A novel binaphthalene-based copolymer (EO-PN) which containing alternating ionic conductive and light-emitting blocks on the main chain was designed and synthesized in order to overcome phase separation problem between the polar ionic conductive and the apolar conjugated polymers in the traditional light-emitting electrochemical cells. Its chemical structure was characterized and photoluminescent property was investigated. Thermal analysis showed that the decomposition temperature of copolymer is over 390℃. The copolymer is a typical violet light-emitting material with a maximum photoluminescent emitting peak at 395 nm.
