Self-host heteroleptic green iridium dendrimers: achieving efficient non-doped device performance based on a simple molecular structure

Self-host heteroleptic green iridium(III) dendrimers have been designed and easily synthesized. Through tuning the carbazole dendron density, high efficiency is achieved using these dendrimers with a simple molecular structure as the emitting layer for the non-doped organic light-emitting diodes.
