COUMARIN DERIVATIVES HAVING CU(II) ION SELECTIVITY, METHOD FOR PREPARING THEREFOR, DETECTING METHOD AND FLUORESCENCE SENSOR USING THE SAME

摘要

PURPOSE: A coumarin derivative including a copper ion detecting property is provided to use the derivative as a high-sensitivity fluorescence crane sensor for detecting copper ion with an excellent fluorescence emission phenomenon. CONSTITUTION: A coumarin derivative marked as the chemical formula 1 includes a copper ion detecting property. The coumarin derivative is produced by reacting 7-diethylaminocourmarin-3-aldehyde and 4-amino-5-phenyl-4H-1,2,4-triazole-3-thiol. The detection of a copper ion is performed by measuring the change of fluorescence by the formation of a complex of the coumarin derivative and the copper ion. A selective detection method of the copper ion comprises the following steps: radiating a solution including a metal ion after adding a coumarin derivative solution to excite the solution; and measuring the fluorescence emitted from the solution.
