聚合物主体材料由于具有易加工,成本低等优点,对于实现高性能的蓝光和白色旋涂器件有重要意义,因而备受关注。本文通过Yamamoto反应合成了一种建立在四苯基硅上的聚咔唑类主体材料P1CzSi,合成的比例咔唑对四苯基硅为95:1。采用FT-IR,GPC等对聚合物结构进行表征,其重均分子量为7.3x103,分子量分布为1.17。利用UV-Vis,PL和CV等研究了聚合物的光学和电化学性能,结果表明,聚合物的荧光最大发射峰位于417nm处,不仅发深蓝色光,而且具有宽的能带隙(3.40 eV),是一种理想的磷光聚合物主体材料。
Polymer host materials due to its ease of processing, low cost and other advantages for the realization of high-performance blue and white spin-on devices is of great significance, and therefore attracted much attention. In this paper, a polycarbazole host material P1CzSi based on tetraphenylsilane was synthesized by Yamamoto reaction. The ratio of synthesized carbazole to tetraphenylsilane is 95: 1. The polymer structure was characterized by FT-IR, GPC and the like, with a weight average molecular weight of 7.3 × 103 and a molecular weight distribution of 1.17. The optical and electrochemical properties of the polymers were investigated by UV-Vis, PL and CV. The results showed that the maximum emission peak of the polymer was located at 417nm, which not only produced deep blue light but also had a wide band gap (3.40 eV) , Is an ideal phosphorescent polymer host material.
