A reversible rhodamine-based sensor (L1) capable of undergoing excimer-fluorescent resonance energy transfer (E-m-FRET) was designed and synthesized using a ditopic receptor strategy. Addition of Cu2+ ions to a solution of L1 induced a ring-open conformation of spirolactam (E-m-FRET ON), whilst ring closure was induced upon addition of CH3COO- (E-m-FRET OFF).
