Fluorescence “ON–OFF–ON” response in the formation of a tetrahedral anionocage and encapsulation of halogenated hydrocarbons†
Abstract
A three-model fluorescence “ON–OFF–ON” system, from a tris-bis(urea) anion ligand (LMe) to anionocage 1Me and then to the host–guest complex, in response to anion coordination and halogenated hydrocarbon encapsulation, was established.
