Luminescent complexes made from chelating isocyanide ligands and earth-abundant metals

Abstract

In this invited frontier article, recently discovered d⁶ and d¹⁰ complexes with long-lived metal-to-ligand charge transfer (MLCT) excited states are highlighted. Chelating diisocyanide ligands give access to emissive Mo(0) and Cr(0) complexes with d⁶ electron configuration exhibiting photophysical properties similar to those of Ru(II) polypyridines or cyclometalated Ir(III) complexes. With Ni(0), these ligands yield luminescent tetrahedral d¹⁰ complexes similar to isoelectronic Cu(I) bis(diimine) compounds.
