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.

由螯合异氰酸酯配体和地球上丰富的金属制成的发光络合物

在这篇受邀的前沿文章中，着重介绍了最近发现的具有长寿命金属到配体电荷转移（MLCT）激发态的d ⁶和d ¹⁰配合物。螯合二异氰化物配体可访问具有d ⁶电子构型的发光Mo（0）和Cr（0）配合物，这些配合物表现出类似于Ru（II）多吡啶或环金属化Ir（III）配合物的光物理性质。与Ni（0），这些配体产生类似于等电子Cu（I）双（二亚胺）化合物的发光四面体d ¹⁰配合物。
