A facile color-tuning strategy for constructing a library of Ir(iii) complexes with fine-tuned phosphorescence from bluish green to red using a synergetic substituent effect of –OCH3 and –CN at only the C-ring of C^N ligand

Abstract

–OCH₃ and –CN will show a favorable synergetic substituent effect on the color-tuning direction when they are grafted at the meta- and para-sites of the C-ring of the C^N ligand.
