An Ir complex having a pyridyl triazole ligand substituted with at least one substituent on its pyridyl ring, and a light emitting material comprising such Ir complex. Such light emitting material was found to have a significantly enhanced photophosphorescence quantum yield and hypsochromic blue shifted photophosphorescent emission over other Ir complexes with a pyridyl triazole ligand having no substituent in its pyridine ring. Use of such light emitting material and an organic light emitting device including the same.

The present invention relates to light emitting materials including a novel Ir complex having a pyridyl triazole ligand substituted with at least one substituent on its pyridyl ring. Such light emitting materials were found to have a significantly enhanced photophosphorescence quantum yield and hypsochromic blue shifted photophosphorescent emission over other Ir complexes with a pyridyl triazole ligand having no substituent in its pyridine ring. The present invention further relates to the use of such light emitting materials and an organic light emitting device including the same.
