Abstract
Device performances of solution processed blue phosphorescent organic light-emitting diodes were studied using a high triplet energy host material soluble both in alcohol and aromatic solvents. 6-(Carbazole-9-yl)benzofuro[2,3-b]pyridine was used as the alcohol and aromatic solvent compatible triplet host material and the effect of solvent on the device performances of blue phosphorescent organic light-emitting diodes was investigated. Toluene and 2-propanol were effective as the solvent materials for the host and high external quantum efficiencies of 11.0% and 11.1% were achieved in the blue devices processed from toluene and 2-propanol, respectively.
