A novel supramolecular metallogel-based high-resolution anion sensor array

Abstract

A novel anion sensor array based on supramolecular metallogels has been developed. It could accurately identify CN(-), SCN(-), S(2-) and I(-) in water. Interestingly, this sensor array is based on a novel design approach termed "competitive coordination control AIE mode" to develop anion-responsive gels which need only one synthesized gelator G1.
