چکیده انگلیسی
A new phenylbenzimidazole derivatized fluorescent sensor (L) with 2-picolylamine as Zn2+ chaltor was designed and prepared. In buffered water solution (HEPES 10Â mM, pH 7.4), sensor L displays highly selective, sensitive and ratiometric fluorescent recognition to Zn2+ based on inhibition of excited-state intramolecular proton transfer (ESIPT). In addition, the resultant L-Zn2+ complex exhibits ratiometric responses to S2â with excellent selectivity via S2â induced Zn2+ displacement approach. The results demonstrate that L can serve as a ratiometric fluorescent sensor for relay recognition of Zn2+ and S2â in water at physiological pH.
