Cao, Hongtao published the artcileAn orange iridium(III) complex with wide-bandwidth in electroluminescence for fabrication of high-quality white organic light-emitting diodes, Computed Properties of 2622-67-5, the publication is Journal of Materials Chemistry C: Materials for Optical and Electronic Devices (2013), 1(44), 7371-7379, database is CAplus.

A novel Ir(III) (pbi)2Ir(biq) with a strong orange emission at 573 nm was synthesized, which showed a high luminescence quantum yield (PLQY) of 45% in CH2Cl2 at 298 K. The quantum chem. calculations together with the photophys. properties indicated that the transition incorporation of 3MLCT (metal-to-ligand charge transfer), 3LLCT (ligand-to-ligand charge transfer) mixed with 3LC (ligand-centered 3π-π*) characters contributed to the emission of (pbi)2Ir(biq). Cyclic voltammetry (CV), TGA and DSC were then performed to study its electrochem. and thermal properties for fabrication of electroluminescent devices. (pbi)2Ir(biq) exhibited wide-bandwidth in electroluminescence (EL) of its orange electroluminescent devices, which made it effectively available to fabricate high-quality two-element white organic LEDs (WOLEDs). The resultant WOLED possessed a high current efficiency (ηc) of 22.1 cd A-1 and power efficiency (ηp) of 25.5 lm W-1 with a high color rendering index (CRI) of 80. The WOLED retained a favorable ηp of 10.9 lm W-1 and ηc of 16 cd A-1 at a high luminance of 1000 cd m-2. This WOLED exhibited a qualified R9 of 13 and Duv of -0.0013, and these values together with the high CRI conformed to the required standard for lamp illumination of the ENERGY STAR.
