Highly selective fluorescent sensing for CN in water: utilization of the supramolecular self-assembly

Author affiliations

Abstract

A simple 4-amino-3-hydroxynaphthalene-1-sulfonic acid is demonstrated to fluorescently sense CN in water based on the mechanism of supramolecular self-assembly. This work provides a novel approach for the selective recognition of CN anions. The detection limit of the sensor towards CN is 3.2 × 10−7 M, and other anions, including F, Cl, Br, I, AcO, H2PO4, HSO4 and ClO4, had nearly no influence on the probing behavior. Notably, the test strips based on S4 were fabricated, which could act as convenient and efficient CN test kits.
