“…Organosensors, through reversible interactions, present an avenue into various applications such as resettable logic gate systems [28][29][30][31], molecular security devices [32,33], micellar devices [34,35], dual sensors [36,37], corrosion inhibitors [38], fabrication of materials and polymers, etc. [39,40]. The optically and chemically stable naphthalene substituted-1,2,3-triazole molecule, NpTP ((2-(4-(naphthalen-2-yl)-1H-1,2,3-triazol-1-yl)phenol, Scheme 1) described herein is produced with straightforward synthesis, targeted design, and sensitive as well as selective ion-recognition properties.…”

Detailed Nuclear Magnetic Resonance (NMR) spectroscopy investigations on a novel naphthalene-substituted 1,2,3-triazole-based fluorescence sensor provided evidence for the "turn-on" detection of anions. The one-step, facile synthesis of the sensors was implemented using the "Click chemistry" approach in good yield. When investigated for selectivity and sensitivity against a series of anions (F − , Cl − , Br − , I − , H 2 PO 4 − , ClO 4 − , OAc − , and BF 4 − ), the sensor displayed the strongest fluorometric response for the fluoride anion. NMR and fluorescence spectroscopic studies validate a 1:1 binding stoichiometry between the sensor and the fluoride anion. Single crystal X-ray diffraction evidence revealed the structure of the sensor in the solid state.

“…A unique polymer poly(MMA‐co‐VNT) 7 with different functional units, a predetermined molecular weight, and a narrow molecular‐weight distribution was synthesised by copolymerising a styryl‐type monomer, 2‐(4‐vinylbenzyloxy)‐1‐naphthaldehyde thiosemicarbazone (VNT) with methyl methacrylate (MMA) . This polymer was examined for the detection of anions, for which it showed a high selectivity to F − ions over other anions.…”

Computers have become smarter, smaller, and more efficient due to the downscaling of silicon-based components. Top-down miniaturisation of silicon-based computer components is fast reaching its limitations because of physical constraints and economical non-feasibility. Therefore, the possibility of a bottom-up approach that uses molecules to build nano-sized devices has been initiated. As a result, molecular logic gates based on chemical inputs and measurable optical outputs have captured significant attention very recently. In addition, it would be interesting if such molecular logic gates could be developed by making use of ion sensors, which can give significantly sensitive output information. This review provides a brief introduction to anion receptors, molecular logic gates, a comprehensive review on describing recent advances and progress on development of ion receptors for molecular logic gates, and a brief idea about the application of molecular logic gates.
