Abstract

Abstract The photophysical properties of wire-type compounds based on a photosensitizing Ru II complex linked to an electron-accepting bipyridinium or diazapyrenium group have been studied with the aim of designing light-driven molecular machines based on pseudorotaxanes (shown schematically). As an outcome, the photoinduced dethreading of a pseudorotaxane formed by a crown ether ring and one of the investigated wire-type ...
