An electron transporting moiety (1,3,4-oxadiazole) and a hole transporting moiety (carbazole) were combined to create 2-(4-biphenylyl)-5-(4-carbazole-9-yl)phenyl-1,3,4-oxadiazole (CzOxa), a three layer device with a configuration of ITO/TPD(50 nm)/CzOxa(40 nm)/AlQ(40 nm)/Mg0.9Ag0.1(200 nm)/Ag(80 nm) which exhibited a blue emission peak at ∼470 nm (x
= 0.14, y
= 0.19) with a maximum luminance of 26200 cd m−2 at a drive voltage of 15 V and a maximum luminous efficiency of 2.25 lm W−1.
电子传输部分(1,3,4-恶二唑)和空穴传输部分(
咔唑)组合形成2-(4-
联苯基)-5-(4-
咔唑-9-基)苯基-1,3, 4-恶二唑(CzOxa),三层器件,配置为ITO/
TPD(50 nm)/CzOxa(40 nm)/AlQ(40 nm)/Mg0.9Ag0.1(200 nm)/Ag(80 nm)其在〜470 nm处表现出蓝色发射峰(x
= 0.14,y
= 0.19),驱动电压为15 V时,最大亮度为26200 cd m−2,最大发光效率为2.25 lm W−1。
