title: High quantum efficiency in solution and vacuum processed blue phosphorescent organic light emitting diodes using a novel benzofuropyridine-based bipolar host material.
abstract: 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.
