What is 1,3-Bis(N-carbazolyl)benzene?

Description

1,3-Bis(N-carbazolyl)benzene, known as mCP, with a high triplet energy (ET ?= 2.91 eV) and a very deep highest occupied?molecular orbital (HOMO) level, is often used as host materials for efficient blue phosphorescent light-emitting diodes. Kawamura et al. demonstrated that the photoluminescence internal quantum yield of the blue emitter of FIrpic could approach nearly 100% when doped into the wide energy gap host of mCP .
