摘要:
An iridium phosphorescent material comprises an iridium-containing core metal and a phenyl-pyridine ligand which is a bidentate ligand of the central metal and in which a steric hindrance phenyl group is introduced, wherein the steric hindrance phenyl is introduced at the ortho position of the phenyl group of the ligand. The present application relates to an iridium phosphorescent material comprising a phenylpyridine ligand in which a steric hindrance functional group is introduced, a method for preparing the same, and the photophysical properties of the material.
