Abstract
The present invention relates to a novel iridium complex into which carbazole-substituted pyridine derivatives and various substituents-substituted phenyl derivatives are introduced as main ligand and a electrophosphorescence diode containing the same as a dopant of a light-emitting layer. When the iridium complex according to the present invention is applied to an organic light-emitting diode, the heat-resistance property and the light-emitting property can be significantly improved as well as the light-emitting efficiency and the like can be significantly improved by doping the iridium complex compound into the light-emitting layer as compared to the conventional organic light-emitting diode.
