摘要：

A new simple bifunctional chemosensor 1 based on rhodamine was synthesized by hydrazide and formylformic acid,which could detect Cuand Hgvia dif ferent detecting methods in CH3 CN-HEPES buffer solution(20 mmol/L,pH 7.4)(1:9,v/v) respectively.When sensor 1 bound with Cu,it showed a colorimetric change,while a selective enhancement in fluorescence occurred upon 1 binding with Hg,resulting from the spirolatam-ring opening process.The binding modes of 1 with Cuand Hgwere investigated based on UV,fluorescence change,ESI-Mass and Job’s Plot data.Moreover,sensor 1 could selectively detect target ion in a mixed solution of Cuand Hg,and the two metal ions do not inte rfere with each other in the process of detecting Cuor Hgwith 1.
