Abstract

Abstract Using 2-(4-trifluoromethyl-6-fluorophenyl) pyridine (tfmfppy) as the cyclometalated ligand and tetraphenylimidodiphosphinate (tpip) derivatives as ancillary ligands, three iridium complexes (1: Ir (tfmfppy) 2 tpip; 2: Ir (tfmfppy) 2 ftpip, ftpip= tetra (4-fluorophenyl) imidodiphosphinate; 3: Ir (tfmfppy) 2 tfmtpip, tfmtpip= tetra (4-trifluoromethylphenyl) imidodiphosphinate) showing phosphorescence at 514, 513 and 508 nm in CH 2 Cl 2 ...
