以苯磺酰肼和4-二苯胺基苯甲醛为原料, 通过缩合反应设计和合成了一种新型磺酰腙汞离子(Hg2+)探针N'-(4-(二苯氨基)亚苄基)苯磺酰腙(S1). 在二甲基亚砜(DMSO)/H2O (VV=7∶3, pH=7)溶液体系中,S1对Hg2+展示出快速响应、高选择和高荧光灵敏性. 通过1H NMR和HRMS探究了可能的机理. 聚丙烯酰胺(PAM)掺杂S1 (PAMS)对Hg2+有高的吸附性能, 其去除率达到99.99%, 并且在紫外灯下通过肉眼很容易区分. 通过扫描电子显微镜(SEM)观察了PAMS吸附前后的微观形貌. 此外, S1具有优异的生物相容性, 可以极好地检测HeLa细胞中的Hg2+.

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.
