Abstract

Abstract Two novel cyclometalated iridium (III) complexes, Ir (pcl) 2 (pic) and Ir (pcl) 2 (fpic)(pcl: 3-phenylcinnoline, pic: picolinic acid, fpic: 5-fluoro-2-picolinic acid) were synthesized and characterized by FTIR, 1 H NMR spectroscopy, UV-vis, PL, and MALDI- TOF. These two Ir-complexes geometry were predicted using the Sparkle/PM6 model and suggested to a chemical environment of very low symmetry around the Ir ions (C 1). The ...
