Özet
2,3-Indoledione 3-thiosemicarbazone (TSCI) and a novel compound 3-(2-(4-(4-phenoxyphenyl)thiazol-2-yl)hydrazono)indolin-2-one (FTHI) were synthesized with high yield and characterized by spectroscopic techniques. The complexation behaviors of TSCI and FTHI for various anionic species (F-, Cl-, Br-, l(-), NO2-, NO3-, BzO(-), HSO4-, ClO4-) in CH3CN were investigated and compared by UV-vis spectroscopy, cyclic voltammetry and H-1 NMR titration techniques. FTHI showed high degree of selectivity for fluoride over other anions. This selectivity could be easily observed by the naked eye, indicating that FTHI is potential colorimetric sensor for fluoride anion. (C) 2014 Elsevier B.V. All rights reserved.
