Fluorescence switches are mol. systems contg. a light-emitting fragment whose activity can be quenched/revived reversibly, at will, through an external parameter, i.e., a change of pH or the variation of the redox potential. Fluorescence switches can be static (the emission of the fluorophore is switched ON/OFF by a bistable covalently linked control unit) or dynamic (the change in fluorescence is accompanied by an oriented mol. motion). Of the latter class of switches, the authors will consider the cases (i) of a metal scorpionate and (ii) of systems in which a metal is reversibly translocated between two nonequivalent compartments of a ditopic ligand.

Abstract
Fluorescence switches are mol. systems contg. a light-emitting fragment whose activity can be quenched/revived reversibly, at will, through an external parameter, i.e., a change of pH or the variation of the redox potential. Fluorescence switches can be static (the emission of the fluorophore is switched ON/OFF by a bistable covalently linked control unit) or dynamic (the change in fluorescence is accompanied by an oriented mol. motion). Of the latter class of switches, the authors will consider the cases (i) of a metal scorpionate and (ii) of systems in which a metal is reversibly translocated between two nonequivalent compartments of a ditopic ligand.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
