A novel naphthaldehyde–based colorimetric and fluorogenic molecular sensor PHNAP [(E)–1–(((4–(phenylamino)phenyl)imino)methyl)naphthalen–2–ol] was developed for the recognition of Cu2+ with outstanding selectivity. After treatment with Cu2+, the PHNAP showed remarkable color transforms from ''yellow'' to ''colorless'' under UV–cabin and ''yellow'' to ''pink'' under daylight. Under the optimum sensing conditions, Cu2+ was selectively recognized and sensitively determined with a nanomolar detection limit (6.61 nM; 3σ/K). The PHNAP showed very fast and Cys-reversible response for Cu2+. The Job's plot and TOF–MS data were gathered to authenticate the mechanism of the binding. The DFT calculations also confirmed the proposed sensing phenomenon. Furthermore, PHNAP–based portable test kits were simply fabricated for the visual recognition of Cu2+. The PHNAP was used in diverse samples for the quantitatively recognition of Cu2+; likewise, the smartphone appliance was successfully performed without the aid of any sophisticated tool and the outstanding visual response of PHNAP.
