Fang, Chung-Hong published the artcileIridium(I) pyridyl azolate complexes with saturated red metal-to-ligand charge transfer phosphorescence; fundamental and potential applications in organic light-emitting diodes, Recommanded Product: 2-[5-(Trifluoromethyl)-1H-1,2,4-triazol-3-yl]pyridine, the publication is Chemistry – A European Journal (2007), 13(9), 2686-2694, database is CAplus and MEDLINE.

Preparation of neutral metal complexes [(cod)Ir(fppz)] (fppz = 3-trifluoromethyl-5-(2-pyrdiyl)pyrazole, 1), [(cod)Ir(bppz)] (bppz = 3-tert-butyl-5-(2-pyridyl)pyrazole, 2), [(cod)Ir(fptz)] (fptz = 3-trifluoromethyl-5-(2-pyridyl)triazolate, 3) and [(cod)Ir(bptz)] (bptz = 3-tert-butyl-5-(2-pyridyl)triazolate, 4), bearing one cod ligand and a pyridyl azolate chelate are reported. A single-crystal x-ray diffraction study of 3 reveals the expected distorted square-planar geometry. The lowest absorption band consists of IrI atom increased triplet dπ → π* transitions (3MLCT), the assignment of which is firmly supported by the theor. approaches. Complexes 1–4 exhibit weak phosphorescence in degassed solution at room temperature, whereas much more intense, solid-state phosphorescence appears in the range 622-649 nm. The pure MLCT emission was used as a prototypical model to address its remarkable spectral differences from the IrIII isoquinoline pyrrolide complex (5), which has mainly 3ππ phosphorescence. Complex 3 was used as a dopant to fabricate red-emitting phosphorescent organic light-emitting diodes (OLEDs). For the 7% doped device, a maximum brightness of 3010 cd m-2 was achieved at an applied voltage of 15 V and with CIE coordinates of (0.56, 0.33), demonstrating for the 1st time the potential of neutral IrI complexes in OLED applications.
