The OLED with TPD(BTPA)4 as hole transport material achieved the highest CEmax of 5.83 cd A−1 compared small molecular HTMs (Mw < 6000) with identical structure, especially operated at high current, which is due to the outstanding thermal stability.
使用
TPD(
BTPA)作为空穴传输材料的OLED,在高电流下表现出色,其最高CEmax达到了5.83 cd A-1,相比于具有相同结构的小分子HTMs(Mw < 6000),这是由于其出色的热稳定性。
