Synthesis, characterization and photophysical properties of cyclometalated Ir (III)‎-di-μ-chloro-bridged dimer based on 2-phenylpyridine derivatives

الملخص EN

New cyclometalated Iridium (III) complexes of 4- naphthalen-1-yl-2-phenyl-pyridine and 5-naphthalene- 1-yl-2-phenylpyridine were synthesized and characterized.

Substitution on the pyridine ring of C^N ligands was used to alter the electronic properties of these complexes.

The (C^N) 2Ir (μ-Cl2) I r(C^N) 2 complexes show phosphorescence with good quantum yields and the emission of these complexes were 530- 531 nm.

All the ligands and complexes were characterized by 1H, 13C NMR, MALDI-MS and CHN analysis.
