摘要: | 以9-(五苯代苯)卡唑為核心,利用Suzuki Coupling及Horner-Wadsworth-Emmons反應與不同單體聚合形成高分子P1~P8,並在高分子主鏈中分別掺混2mol%的1,4-bis(2-bromo-phenylenevinylene)benzene(簡稱OPV)與Benzothiadiazole,觀察其對高分子光電性質的影響;共聚高分子由於側鏈中含有五苯代苯而使的分子對稱性降低,轉動自由能提升,使玻璃轉換溫度有明顯的提升,在裂解溫度上也有不錯的表現。此外將合成的高分子進行有機電激發光二極體的元件製作並對其特性加以討論。 Copolymers of carbazole and fluorene with dendrimer side groups were synthesized using Suzuki Coupling and Horner-Wadsworth-Emmons reaction. Furthermore, 2mol% of benzothiadiazole and 1,4-bis(2-bromostyryl)benzene (OPV) were introduced into the copolymers. The effects of these two groups on optical and electrical properties of the copolymers were investigated. Copolymers with dendrimer side groups have higher Tg since the huge side groups make it difficult to rotate and move. At last, polymer light emitting diodes were fabricated and the performance of the devices was thoroughly investigated. |
