Syntheses of molecular wires containing redox center: Reversible redox property and good energy level matching with Au electrode

Molecular wires with tetrathiafulvalene (TTF) as redox center were synthesized and characterized. UV–vis spectra and cyclic voltammetry showed these wires had good reversible redox behavior under ambient conditions and their HOMO energy levels (∼−5.0 eV) matched well with the Fermi level of Au (∼−5.1 eV).
