An efficient colorimetric chemosensor with a thiourea binding site and 2-amino-6-nitrobenothiazole as a signaling unit has been synthesized by dithiocarbamate approach. The chemosensor has been utilized for selective recognition of fluoride and acetate anions in dry DMSO solution by UV-vis and H-1 NMR titration experiments. The chemosensor has shown naked-eye sensitivity for both the anions in solution. (C) 2009 Elsevier B.V. All rights reserved.
