Abstract:
Provided is a cyclometalated transition metal complex represented by Formula 1, Formula 2 or Formula 3: By including a new ancillary ligand, the cyclometalated transition metal complex can efficiently emit red light using a phosphor by intersystem crossing (ISC) of excitons to triplet states and then metal to ligand charge transfer (MLCT). An organic light emitting device prepared using the transition metal compound shows high luminous efficiency and high external quantum efficiency.
