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。
Polymeric host =aterials have attracted extensive attention because of their inexpensive solution-processing techiniques and their potential application for blue and white OLEDs. In this paper, We have synthesized one tetraarylsilaae-based carbazole poly=eric host materials P1CzSi, with the ratio of carbazole to tetraarylsilane (95. 5), through ~ar~amoto coupling reaction. The structure of the obtained polymer was characterized by FT-IR, GPC, TGA, et. The molecular weight and poly dispersity of the polymer were 7.3xl0~and 1.17, respectively. The optical and electrochemical properties, revealed by IN-Vis and PL, show that the polymer had a maximum peak of fluorescence emission at 417 nm, not only emitted deep blue light emitting, but also have large bandgap (3.40 eV) , which is expected to good phosphorescent polymer host eaterials.
