Controlling Redox and Wirelike Charge-Delocalization Properties of Dinuclear Mixed-Valence Complexes with MCp*(dppe) (M = Fe, Ru) Termini Bridged by Metalloporphyrin Linkers.

ABSTRACT: Four dinuclear organometallic molecular wire complexes with diethynylmetalloporphyrin linkers 1 ^MM' , [5,15-bis{MCp*(dppe)ethynyl}-10,20-diarylporphinato]M' (Cp* = η⁵-C₅Me₅; dppe = 1,2-bis(diphenylphosphino)ethane; M/M' = Fe/Zn (1 ^FeZn ), Ru/Zn (1 ^RuZn ), Fe/Ni (1 ^FeNi ), Ru/Ni (1 ^RuNi ); aryl = 3,5-di-tert-butylphenyl), are synthesized and characterized by NMR, CV, UV-vis-NIR, and ESI-TOF mass spectrometry techniques. Electrochemical investigations combined with electronic absorption spectroscopic studies reveal strong interactions among the electron-donating, redox-active MCp*(dppe) termini and the metalloporphyrin moieties.
