简单介绍


ossila材料CbBPCb  的详细介绍

CbBPCb, having similar structure to the well-known host material mCBP, is a highly efficient carboline-based phosphorescent host with oligophenyl spacer. CbBPCb is bipolar, but shows a higher electron mobility of 3.83×10-6 cm2 V-1 s-1 than its hole mobility of 6.33×10-7 cm2 V-1 s-1.

With a wide bandgap and high triplet energy level, CbBPCb can achieve high quantum efficiencies of over 30.0% in blue phosphorescent organic light emitting diodes. This is due to the host-guest energy transfer, balanced charge injection / transporting and effective exciton confinement within the emitting layer [1, 2]
