简要本文合成了三种均三嗪衍生物TPTPA、TITPA和TCTPA，并利用其在电学和光学特性，将其作为发光/电子传输层材料制作有机电致发光器件(OLEDs). 其中，TCTPA具有比TPTPA和TITPA更高的荧光量子产率(PL). 从TPTPA到TCTPA其最低未占据轨道能级(LUMO)逐渐减少，这说明了TCTPA由于其共轭结构的增大，具有更高的电子迁移率. 以TCTPA作为发光/电子传输层的无掺杂OLED器件，在20V时亮度达到最大值2 612 cd/m2，其最大亮度效率和最大功率效率分别为1.72 cd/A 和1.35 lm/W. 将Ir(PPy)3、PVK、PBD等化合物，分别掺杂到以TCTPA为发光/电子传输层的OLED器件中，均展示出比无掺杂器件更高的亮度及效率.
Three 1, 3, 5-triazine derivatives TPTPA, TITPA and TCTPA were synthesized and their electrical, photophysical properties were characterized with respect to their application as emitting layer/electron-transporting layer in Organic Light-Emitting Diodes (OLEDs). Compound TCTPA show higher PL quantum yield (PL) than TPTPA and TITPA. The decrease of LUMO from TPTPA to TCTPA show that TCTPA with extended conjugation exhibits better electron mobility. Among the undoped devices, device with TCTPA as the emissive layer/electron-transporting layer exhibits a maximum brightness of 2 612 cd/m2 at an applied voltage of 20 V, and the maximum luminance efficiency, highest power efficiency were 1.72 cd/A and 1.35 lm/W. Devices doped with Ir(PPy)3, PVK or PBD all show better brightness and efficiency.
