Abstract

Abstract A proposal for a redox-linked conformational gate to proton translocation—a proton pump gate—based upon a transition-metal redox-switchable hemilabile ligand (RHL) system is made. Consideration of the requirements for such a system reveals copper (II) to be the ideal metal centre. To test the proposal and, thereby, to provide an artificial proton pump gate, the copper coordination chemistry of three tris (pyridylmethyl) amine (tpa) ...
