摘要：
Three greenish-blue iridium (III) phosphorescent complexes with the molecular structure of [Ir(PPPY)(2)(PPh3)L] (Hpppy = 2-(4-phenoxyphenyl)pyridine; L = Cl-, NCS-, NCO-) were synthesized and characterized. Their photoluminescence spectra are significantly blue-shifted after introducing the strong-field ancillary ligand triphenylphosphine. These compounds exhibit emission peaks in the range of 474-479 nm in solutions at 298 K with quantum yields up to 0.33. The organic light-emitting diodes (OLEDs) were fabricated by thermal evaporation with complex 3. The best OLED D3 was obtained with turn-on voltage of 4.3 V, maximum luminance of 11931 cd m(-2) under 15.7 V, highest luminance efficiency (eta(L)) as 16.6 cd A(-1), power efficiency (eta(P)) as 12.2 Im W-1 and external quantum efficiency (EQE) as 5.6%.
