A series of square-planar nickel(II) donor-acceptor complexes exhibiting ligand-to-ligand charge-transfer (LL′CT) transitions have been prepared and characterized by a battery of structural, spectroscopic, electrochemical, and computational methods. Through appropriate choice of the donor, complexes of the type (donor)Ni(bpy) have been prepared with absorption profiles that are tunable throughout the visible and near-IR regions of the solar spectrum and that manifest strongly reducing excited states. Experiments aimed at developing these complexes as excited-state electron transfer reagents will be presented.
