A novel sulfonylhydrazone Hg2+ probe (4-(diphenylamino)benzylidene)benzenesulfonyl hydrazone (S1) was designed and synthesized by condensation reaction between benzenesulfonyl hydrazide and 4-(diphenylamino)benzaldehyde. Probe S1 exhibited a rapid response time, high selectivity and sensitivity fluorescent response to Hg2+ in dimethyl sulfoxide (DMSO)/H2O (VV=7∶3, pH=7) solution. The possible mechanism was studied by1H NMR and HRMS. Polyacrylamide (PAM) doped S1 (PAMS) had high adsorption for Hg2+ with removal rate of 99.99% and could easily be distinguished by the naked-eye in UV lamp. And, the micro-morphology of PAMS before and after adsorption was observed by scanning electron microscope (SEM). In addition, probe S1 had excellent biocompatibility and could primely detected Hg2+ in HeLa cells.
