This report describes an on-off module of a fluorescent probe for selectively sensing of Fe(II) and Fe(III) ions by a single chemosensor with unique output optical response and is being reported for the first time. The probe 8-methylquinolinyl-1,2,3-triazoly1 silatrane (QTS) was efficiently developed using click silylation route, followed by transetherification of silane. Moreover, the color change in probe QTS by response of this colorimetric sensor can be visualized by naked eye. The anti-quenching response for quenched QTS-Fe3+ fluorescence spectra by addition of H2PO4- ions in the MeOH/H2O solvent system results into reversion of fluorescence maximum. These fluctuations in spectral response, under electronic behavior, can be viewed to mimic as NOR and IMPLICATION logic gate. (C) 2015 Elsevier B.V. All rights reserved.
