Highly efficient iridium(III) phosphors with 2-(4-benzylphenyl)pyridine-type ligand and their high-performance organic light-emitting diodes

A series of new cyclometalated iridium(III) complexes containing a methyl or trifluoromethyl substituted 2-(4-benzylphenyl)pyridine molecular framework have been synthesized and characterized. All these complexes are amorphous and possess excellent thermal...
