Two novel compounds, water-soluble 1,8-naphthalimide dendrons tert-butoxycarbonyl-{N,N-bis{3,5-bis{2-(4- tert-butylphenyl)-5-[1,3,4]-oxadiazolyl}-styryl-1,8-naphathlimide}-ethylaminocarbonylethyl}ethylamino}-1,8-naphthalimide (DON) and 4-piperidyl-9-ethylamino-{N,N-bis{3,5-bis{2-(4-tert-butylphenyl)-5-[1,3,4]-oxadiazolyl}-styryl-1,8-naphathli- mide}-ethylaminocarbonylethyl}ethylamino}-1,8-naphthalimide (DOPN) were synthesized and characterized by 1H NMR, 13C NMR and HRMS techniques. Fluorescence spectra of DON and DOPN in solid, tetrahydrofuran and aqueous were measured. The results demonstrated that DON and DOPN performed orange fluorescence in the solid state and the maximum emission wavelength were 566 and 561 nm, respectively. Blue-green fluorescence was observed in tetrahydrofuran (THF) solution. The maximum absorption wavelengths were 399 and 395 nm, the maximum emission wavelengths were 489 and 492 nm, and the quantum yields were 28.2% and 20.4%, respectively. Besides, the maximum absorption wavelengths were 406 and 408 nm, and the maximum emission wavelength were 563 and 552 nm in aqueous. Two water-soluble 1,8-naphthalimide dendrons were applied for fluorescence imaging in Hela living cells. In addition, metal ion probe behavior of DON was detected. And DON exhibitted a selectivity for tin ion. With the incresing of concentration of tin ion, fluorescence intensity of DON was enhancing. The number of binding sites between tin ion and DON was 2. In a word, two water-soluble 1,8-naphthalimide dendrons, can be used as a flourescent probe for detection of tin, and can be further applied in living cell imaging.
