dc.description.abstractColorimetric receptors L1, L2 and L3 possessing OH functionality as binding site and NO2 as signalling unit with varied positional substitution of OMe functionality has been designed and synthesised by simple Schiff base condensation reaction. Receptors L1, L2 and L3 showed selective response towards AcO?ion among other interfering monovalent anions viz., F?, Cl?, Br?, I?, NO3 ?, HSO? 4 and H2PO? 4. L2 imparts high selectivity towards AcO? ion assisted by push-pull effect of NO2 and OMe functionality in conjugation with imine linkage. The binding constant for L2 OAc complex was found to be 9.04 נ104 M?2. L2 exhibited a detection limit of 0.61 ppm towards NaOAc. The selectivity of L1 towards Cu2+ ions with a lower detection limit of 1.81 ppm implies the role of electron donating OMe in favouring the coordinative interaction of hetero atoms of L1 with Cu2+ ions. The selective detection of AcO? and Cu2+ ions is further established with OR and INHIBIT logic gate application of receptors L1, L2 and L3 correspondingly. The colorimetric studies reveal the role of OMe functionality in the selective detection of AcO? and Cu 2+ ions in aqueous media. 2017 Informa UK Limited, trading as Taylor & Francis Group.en_US
