| 摘 要： | 以罗丹明B、水合肼及2'-羟基苯乙酮等廉价化合物为原料,经过简单的缩合反应得到可识别Hg~(2+)的荧光探针L,其结构经1HNMR、13CNMR以及HR-MS表征。光谱性能研究表明,探针L在Et OH-H2O(V(Et OH)∶V(H2O)=4∶1,p H 7.0,20 mmol/L HEPES)体系中,对Hg~(2+)具有优异的识别能力,两者的配合比为1∶1,且识别过程可逆。

| Abstract: | A rhodamine-based mercuric ion fluorescent probe L was synthesized expediently by the condensation reaction of several inexpensive compounds such as rhodamine B,hydrazine hydrate and 2'-hydroxyacetophenone,and its structure was confirmed by 1HNMR,13CNMR and HR-MS.Probe L has markedly recognition properties for mercuric ion in EtOH-H2O (V(EtOH) ∶V(H2O) =4∶1,at pH 7.0,20 mmol/L HEPES buffer) solution.The stoichiometry of L-Hg2+ complex was estimated to be 1 ∶ 1 and their recognition process was revisable. |
