Deep-blue phosphorescent iridium complexes with picolinic acid N-oxide as the ancillary ligand for high efficiency organic light-emitting diodes

A new series of highly efficient deep-blue phosphorescent Ir(III) complexes, (F2CH3ppy)2Ir(pic-N-oxide) 6 and (F2CF3CH3ppy)2Ir(pic-N-oxide) 7, based on phenylpyridine (ppy) as th

Important role of ancillary ligand in the emission behaviours of blue-emitting heteroleptic Ir(III) complexes

A series of heteroleptic Ir(iii) complexes composed of 2-(2,4-difluoro-3-(trifluoromethyl)phenyl)-4-methylpyridine (dfCF3) as the main ligand and such ancillary ligands as acetylacetonate [Ir(dfCF3)2(acac)] (acac), picolin

Deep-blue phosphorescent emitters with phosphoryl groups for organic light-emitting diodes by solution processes

The new deep-blue iridium complex, Ir(dppfm)2pic, consisting of a phosphoryl group at the 3'-position of the phenyl ring and a methyl group at the 4-position of pyridine, was synthesized and characterized for applications in organic light-emitting diodes (OLEDs). Ir(dppfm)2pic exhibited an emission peak of 455 nm and high photoluminescence quantum yields of 73 %. Phosphorescent OLEDs based on Ir(dppfm)2pic exhibited a maximum external quantum efficiency of 7.8 % and Commission Internationale de l'Eclairage (CIE) coordinates of (0.15, 0.22).

Synthesis and characterization of blue-emitting Ir(III) complexes with multi-functional ancillary ligands for solution-processed phosphorescent organic light-emitting diodes

A series of Ir(III) complexes, (dfpmpy)2Ir(pic), (dfpmpy) 2Ir(EO2-pic), (dfpmpy)2Ir(pic-N-O), and (dfpmpy)2Ir(EO2-pic-N-O), containing 2-(2,4- difluorophenyl)-4-methylpyridine (dfpmpy) base

Preparation of blue-emitting phosphorescent iridium(III) complex under ultrasound reaction

F2MeIrpic (Iridium(III)bis[2-(2',4'-difluorophenyl)-4-methyl pyridinato-N,C2'] picolinate) was synthesized to develop a blue-emitting phosphorescent Ir(III) complex. The synthesized F2MeIrpic showed sky blue light with the maximum PL peak at 470nm. Genera
