High Quantum Efficiency in Solution and Vacuum Processed Blue Phosphorescent Organic Light Emitting Diodes Using a Novel Benzofuropyridine‐Based Bipolar Host Material

High quantum efficiency in solution and vacuum processed blue phosphorescent organic light emitting diodes are achieved using a new benzofuropyridine based bipolar host material. High quantum efficiencies of 18.0% and 23.0% are obtained in soluble and vacuum evaporable blue devices.
