Xu, Huixia published the artcileSynthesis and photoelectric performances of blue-green emitting iridium phenylpyridine complexes using N,N’-heteroaromatic ancillary ligands, Computed Properties of 219508-27-7, the publication is New Journal of Chemistry (2015), 39(7), 5293-5299, database is CAplus.
Four iridium complexes [(ppy)2IrL] containing different ancillary ligands [HL = 2-(5-R-2H-1,2,4-triazol-3-yl)pyridine, where R = 4-CF3C6H4 (Htfmpptz), 4-FC6H4 (Hfpptz), CF3 (Htfmptz); Hppy = 2-phenylpyridine] were synthesized and characterized. Their mol. structures were identified by x-ray single crystal diffraction. The effects of ancillary ligands on the photophys. and luminescence behaviors were investigated. The emission maximum peaks of (ppy)2Ir(tfmpptz), (ppy)2Ir(fpptz) and (ppy)2Ir(tfmptz) in CH2Cl2 solution appear at 485, 487 and 483 nm, resp. Phosphorescent organic light-emitting devices (PhOLEDs) were fabricated using these complexes doped in CBP as an emitting layer.
