Abstract

• Luminescent cyclometalated rhodium(III) and iridium(III) complexes of the general formula [M(ppy)(2)(NN)][PF(6)], with NN = Hcmbpy = 4-carboxy-4'-methyl-2,2'-bipyridine and M = Rh (1), Ir (2) and NN = H(2)dcbpy = 4,4'dicarboxy-2,2'-bipyridine and M = Rh (3), Ir (4), were prepared in high yields and fully characterized. The X-ray molecular structure of the monocarboxylic iridium complex [Ir(ppy)(2)(Hcmbpy)][PF(6)] (2) was also determined. The photophysical properties of these compounds were studied and showed that the photoluminescence of rhodiurn complexes 1 and 3 and iridium complexes 2 and 4 originates from intraligand charge-transfer (ILCT) and metal-to-ligand charge-transfer/ligand-centered MLCT/LC excited states, respectively. For comparison purposes, the mono-and dicarboxylic acid ruthenium complexes [Ru(DIP)(2)(Hcmbpy)][Cl](2) (5) and [Ru(DIP)(2)(H(2)dcbpy)][Cl](2) (6), where DIP = 4,7-diphenyl-1,10-phenanthroline, were also prepared, whose emission is MLCT in nature. Comparison of the photophysical behavior of these rhodium(III), iridium(III), and ruthenium(II) complexes reveals the influence of the carboxylic groups that affect in different ways the ILCT, MLCT, and LC states.
