| Popis: | Two new fluorescence probes having semicarbazide (DSC) and thio-semicarbazide (DTSC) units have been derived upon reaction with 2-hydroxy-5-methylbenzene-1,3-dialdehyde. Both the probes show excellent selectivity for acetate ion in DMSO medium whereby DTSC generates tricolor emission. The association constants of DSC and DTSC for acetate are 6.6×10(4)M(-1) and 2×10(3)M(-1) respectively with corresponding detection limits, 1.06×10(-7)M and 2.5×10(-6)M. Density functional theoretical (DFT) studies nicely demonstrate the interaction between the DTSC and acetate ion. |
