We report herein the first diaininocyciopent-2-eiioile-based catalytic chernoclosimeter (3) for naked-eye and turn-on fluorescent detections of Cu2 in pure aqueous solution. Compound 3 easily made available from furan-2-carbaldehyde and 2-aminobenzoic acid was found to show a highly selective and sensitive response toward Cu2 by way Of Cu2 -coordination promoted formation of Stenhouse salt and subsequent decomposition to highly fluorescent 2-aminobenzoate.
