Spectrochim Acta A Mol Biomol Spectrosc. 2016 Oct 5;167:78-83. doi: 10.1016/j.saa.2016.05.031. Epub 2016 May 24.A novel chemosensor, 3',3‴,3‴″-(((nitrilotris(ethane-2,1-diyl))tris(azanylylidene))tris(methanylylidene))tris(4-hydroxy-4'-biphenylcarbonitrile) (L) was synthesized and characterized by the combination of (1)H,(13)C, APT, COSY NMR, FT-IR, and elemental analysis. The behavior of the receptor (L) toward different anions was investigated using UV-visible and fluorescence spectroscopy. The receptor (L) indicated an efficient colorimetric "naked-eye" and "turn on" fluorescent response for fluoride and acetate in CH3CN, respectively. Copyright © 2016 Elsevier B.V. All rights reserved.
