A novel sensor molecule 2-hydroxyl-1-naldehyde-N-(4-aminophenyl)-1,8-naphthalimide (H1) based on functionalized naphthalimide Schiff Base derivative was synthesized. H1 was characterized by 1H NMR, 13C NMR and HRMS. Furthermore, its fluorescence properties were studied in dimethyl sulfoxide (DMSO)/H2O (V:V=7:3) solutions. Its maximum emission wavelength was 496 nm. The solution of H1 has yellow-green fluorescence under the UV lamp (365 nm). H1 showed fluorescence-colorimetric dual channel identification ability for Fe3+. With the addition of various metal ions into the H1 solution, only Fe3+ caused the fluorescence of the H1 quenching and the color disappeared. Other cations such as Ag+, Ca2+, Ba2+, Co2+, Ni2+, Cd2+, Pb2+, Zn2+, Cu2+, Mg2+ and Hg2+ could not induce similar response. The results of anti-disturbance experiment demonstrated that other cations can not interfere in the detection of Fe3+. H1 has good sensitivity for Fe3+, the fluorescence and UV-Vis detection limits of the H1 for Fe3+ are 3.04×10-8 and 2.71×10-6 mol·L-1, respectively. Finally, the test strips based on the H1 were prepared, which could conveniently and efficiently detect Fe3+ in water.
