The N-heterocyclic carbene 1,3-di-t-butylimidazol-2-ylidene (dbiy) can function as charge transfer (CT) donor and acceptor if it is coordinated to oxidizing and reducing metals, respectively. The complex (TiCl4)-Cl-IV(dbiy)(2) shows a ligand-to-metal CT absorption at 450 nm whereas Ni-0(CO)(2)(dbiy)(2) is characterized by a metal-to-ligand charge transfer absorption at lambda(max) = 365 nm. While (TiCl4)-Cl-IV(dbiy)(2) is not luminescent, Ni-0(CO)(2)(dbiy)(2) displays a room temperature emission at lambda(max) = 510 nm which is assumed to originate from the lowest-energy MLCT triplet.
