Photoinduced electron transfer in supramolecular ruthenium–porphyrin assemblies

Abstract

We present dynamic supramolecular systems composed of a Ru(ii) complex of the form of [Ru(dtBubpy)₂(qpy)][PF₆]₂ (where dtBubpy is 4,4′-di-tert-butyl-2,2′-dipyridyl and qpy is 4,4′:2′,2′′:4′′,4′′′-quaterpyridine) and zinc tetraphenylporphyrins (ZnTPP), through non-covalent interactions between the distal pyridines of the qpy and the zinc of ZnTPP.
