Potential Solution Processible Phosphorescent Iridium Complexes toward Applications in Doped Light-Emitting Diodes:  Rapid Syntheses and Optical and Morphological Characterizations

A series of carbazol-9-yl end-capped red-emitting heteroleptic iridium complexes was readily synthesized using post Suzuki coupling. The appealing solubility, photoluminescent characteristics, and morphological stability enabled the current heteroleptic iridium complexes to be highly desirable phosphorescent dopant emitters in doped light-emitting diodes for the purpose of resisting molecular aggregations in the doped emitting layers.
