Abstract:
Two new amorphous molecular materials, 2,5-bis(2′,5′-dimethyl-4-triphenylsilyl-phenyl)-[1,3,4]oxadiazole (BDTSO) and 2,5-bis(2′,5′-dimethyl-4-triphenylsilyl-phenyl)-[1,3,4] thiadiazole (BDTST) were synthesized and investigated as hole blocking materials (HBM)
for organic light-emitting diodes. The efficiency of electroluminescent device was improved by using BDTSO instead of BAlq. The current and power efficiency of the device using BDTSO as HBM is 39.6 cd/A and 13.1 lm/W at 10 mA/cm 2 , respectively, which is higher compared to the same
values for devices using BDTST and BAq which are typically used as HBM.
