FLUORESCEIN COMPOUNDS HAVING SELECTIVITY FOR PERBORATE AND METHOD FOR MONITORING PERBORATE USING THE SAME

摘要

PURPOSE: A sensor containing fluorescein-based compound of perborate selectivity and a method for detecting perborate using the same are provided to rapidly detect the perborate and to use the fluorescein-based compound as a selective fluorescent sensor for the perborate. CONSTITUTION: A sensor for perborate includes a compound represented by chemical formula 1. In the chemical formula 1, the R1 to R3 are respectively hydrogen, halogen, hydroxyl, cyano, carboxyl, or C1 to C6 alkyl group. The R4 represents hydrogen, bezothiazole, or benzo imidazole. The R5 represents carbonyl group. The R4 and the R5 forms a ring or a fused ring containing the X and the Z. The R6 to R8 are respectively hydrogen or halogen atoms. The Z represents a nitrogen atom or CR9 and represents a spiro atom to form a ring and a spiro compound containing the X and the Z. The R9 represents hydrogen, halogen, hydroxyl, cyano, or carboxyl group. The R10 and R11 are respectively hydrogen, halogen, or carboxyl functional group. The 12 and the R13 are respectively hydrogen or halogen. The X represents oxygen atom or sulfur atom.
