The simplest molecular chemosensor for detecting higher pHs, Cu2+ and S2- in aqueous environment and executing various logic gates

Research Abstract

The sensory properties of the simplest Probe-1 are reported. Probe-1 exhibits colorimetric and fluorimetric responses towards higher pHs. Also, a borate aqueous solution of Probe-1 (pH = 10) could to detect the presence of Cu2+ in aqueous solution with high selectivity and sensitivity (3 μM). The Probe-1/Cu2+ complex responses selectively towards the presence of S2−, H2PO4- and P2O74- through a de-metallization mechanism, resulting in a fluorescence enhancement of 143%, 97% and 134%, respectively. On the other hand, the Probe-1 absorbance increases significantly only by S2- (131%). Furthermore, Probe-1 executes many logic gates such as XOR, AND, INHIBIT, IMPLICATION, TRANSFER and NOT TRANSFER.
