Abstract: Two urea based colorimetric receptors were developed. The receptor L showed a exclusive selectivity of cyanide over the other anions in acetonitrile solution and exhibited Intramolecular charge Transfer (ICT). It was studied by UV-vis spectroscopy and their binding ability was explored by using Job’s plot and Benesi-Hildbrand routes. From that the receptor L, it recognize CN-anions and it indicates 1:1 stoichiometric ratio and the receptor L 1 (monofluoro substituted) does not recognize any anions. Finally the (difluoro substituted) receptor L shows good sensitivity, selectivity towards cyanide.
