Abstract

A novel dansyl sulfonamide-based fluorescence probe

(E)-5-(dimethylamino)-

-(4-(2-(quinolin-2-ylmethylene)hydrazinecarbonyl)phenyl)naphthalene-1-sulfonamide (DW1) was synthesized for detection of Zn

. UV-Vis

fluorescence and ESI-MS spectra of DW1 were measured to investigate the selective recognition. The results show that the fluorescence intensity increase significantly with high quantum yield (

=0.32) and blue-shift emission from 545 nm to 515 nm after the coordination of DW1 with Zn

manifesting DW1 could detect Zn

sensitively. Moreover

the selective and competitive fluorescent experiments show that DW1 is highly selective for recognition of Zn

over other common metal ions. Spectrophotometric titration and ESI-MS spectrum indicate the formation of a 1∶1 DW1-Zn

complex and the association constant

was calculated as 1.75×10
