Disclosed are a 1,8-naphthalimide derivative, a preparation method therefor and a use thereof. The 1,8-naphthalimide derivative is easy to prepare, and is an enhanced Cu.sup.2+ fluorescent probe, which can detect Cu.sup.2+ by two wavelengths and be applied to almost-all-water systems. According to atitration experiments and blank experiments at 392 nm and 754 nm, the detection limit of the 1,8-naphthalimide derivative of the present invention for Cu.sup.2+ is 2.6368×10.sup.−7 mol/L and 2.0156×10.sup.−7 mol/L, respectively, indicating that same can perform quantitative detection for Cu.sup.2+ with a high selectivity and a high sensitivity by using two wavelengths. In addition, a pH colorimetric switch based on 1,8-naphthalimide can rapidly and reversibly respond to a pH by means of three ways: a maximum absorption wavelength, absorbance and color change. Same has a narrow switching pH range, a good selectivity and a high sensitivity, can be used in almost-all-water systems.
