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(V∶V=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 (V ∶ V=7 ∶ 3,pH=7) solution.The possible mechanism was studied by 1H 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.
