含吡啶基团的双极主体材料的合成、性能与蓝光电致磷光器件研究
摘要
Pyridine derivatives are usually used as electron transport moiety in bipolar host materials or electron transport materials due to their good electron transport ability and high triplet energy. Two new pyridine-containing bipolar materials, named DTPAPPy and DCzPPy, were designed and synthesized by incorporating electron-donating triphenylamine or carbazole and electron-accepting pyridine into one molecular. They showed relatively high triplet energy of 2.64 eV for DTPAPPy and 2.70 eV for DCzPPy, respectively. The blue phosphorescent OLEDs hosted by DTPAPPy and DCzPPy achieved maximum current efficiencies of 15.4 and 25.3 cd/A, respectively.
