摘要
High quantum efficiencies of above 30% in blue phosphorescent organic light emitting diodes are achieved by using novel pyridoindole-based bipolar host materials. A high quantum efficiency of 30.0% is obtained at 100 cd/m 2 by using the new host materials. Copyright © 2013 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim.
