Abstract
A new iridium(III) complex [Ir(cpy)2(prz)], (cpy=9-(pyridin-2-yl)-9H-carbazole; prz=pyrazine-2-carboxylic acid) has been synthesized and characterized. The molecular structure of [Ir(cpy)2(prz)] was confirmed by a single-crystal X-ray diffraction. The iridium metal center adopts a distorted octahedral structure coordinated to two cpy and one prz ligand, showing cis C–C and trans N–N chelate dispositions. The photophysical, electrochemical properties and thermal stability of the complex were investigated. The complex showed green luminescence and good electrochemical stability with high lying HOMO energy levels.
