Highly efficient soluble blue phosphorescent organic light emitting diodes have been developed using a multilayer device structure based on alcohol soluble blue phosphorescent emitting layer. A device structure with double emitting layer and an exciton blocking layer could be fabricated due to orthogonal film formation and a high quantum efficiency of 14.1% and a current efficiency of 30.4 cd/A were achieved in the soluble blue phosphorescent organic light emitting diodes.
