Abstract

A new host material was synthesized for blue phosphorescent organic light emitting diodes (PHOLEDs) by modulating carbazolyl-carbazole and dibenzothiophene groups. In particular, by comparing the characteristics of the two hosts with and without a biphenyl linker, we studied the effects of the biphenyl linker on photophysical properties and on the device performances of a blue emitting phosphorescent dopant. As a result, the newly synthesized host materials were functioned as high efficiency and long lifetime host materials in blue phosphorescent devices and they prolonged life span of the blue devices by 5 times compared to a common mCBP blue host.
