A novel fluorescence probe based on naphthalimide-rhodamine N,N'-rhodamine acyl ethylamino-4-pyridine vinyl-1,8-naphathlimide (PNRh) was synthesized and characterized by 1H NMR, 13C NMR and HRMS techniques. Fluorescence spectra of PNRh in solid, ethanol/water mixed solution were measured. The results demonstrated that PNRh performed luminous yellow fluorescence in the solid state and the maximum emission wavelength was 592 nm. With the increasing of water content, the fluorescence intensity was enhanced in the ethanol/water mixed solution. When the water content reached 100%, the fluorescence intensity got the highest, and the color of the solution turned from slight blue fluorescence to kermesinus fluorescence. In addition, metal ion probe behavior of PNRh was detected. In a word, PNRh, possessed the characteristic of aggregation-induced emission enhancement (AIEE), was a dual-channel fluorescence sensor for detection Hg2+ and Cr3+ ions.

Key words: naphthalimide-rhodamine, aggregation-induced emission enhancement, dual-channel fluorescence probe, mercury ion fluorescence probe, pH fluorescence probe
