Binaphthyl-derived salicylidene Schiff base for dual-channel sensing of Cu, Zn cations and integrated molecular logic gates

Addressing of multiple-metal ions on a single platform

“…These multi-input and multi-output circuits avoid the possible mutual interferences that may arise out of intermolecular interactions [63][64][65][66]. The concept has been well put forward by Wang et al [67] by reporting a binaphthyl bridged salicylidene Schiff base 34, which displayed distinct optical properties on binding with two different transition metal ions viz. Cu 2+ and Zn 2+ .…”

“…(a) The proposed binding modes of dual-channel probe 34 with Zn 2+ and Cu 2+ ions, (b) Truth table and the corresponding logic circuit comprising of two metal ions as inputs and absorption and emission responses as outputs[67].…”

Synthesis, structure and sensing behavior of hydrazone based chromogenic chemosensors for Cu2+ in aqueous environment

“…EDTA (ethylenediaminetetraacetic acid) being a good chelating agent for metal ions like Cu 2+ , can be used as inputs in some molecular logic function [32][33][34]. Here, we have introduced EDTA and Cu 2+ as stimulating inputs to study the molecular logic function with absorbance as output.…”

A new Schiff base as a turn‐off fluorescent sensor for Cu2+ and its photophysical properties

“…The significance of Cu 2+ ions, along with their toxicity encouraged us to develop novel chemosensors based on fluorescence methodology for the selective detection of Cu 2+ ions . Herein, we report a novel Cu 2+ selective fluorescent Schiff base receptor 1 i.e.…”
