  • Title: Novel heterocyclic thiosemicarbazones derivatives as colorimetric and "turn on" fluorescent sensors for fluoride anion sensing employing hydrogen bonding.
    Author: Ashok Kumar SL, Saravana Kumar M, Sreeja PB, Sreekanth A.
    Journal: Spectrochim Acta A Mol Biomol Spectrosc; 2013 Sep; 113():123-9. PubMed ID: 23714188.
    Abstract:
    Two novel heterocyclic thiosemicarbazone derivatives have been synthesized, and characterized, by means of spectroscopic and single crystal X-ray diffraction methods. Their chromophoric-fluorogenic response towards anions in competing solvent dimethyl sulfoxide (DMSO) was studied. The receptor shows selective recognition towards fluoride anion. The binding affinity of the receptors with fluoride anion was calculated using UV-visible and fluorescence spectroscopic techniques.
