Abstract

A label-free fluorescence turn-on approach for the selective sensing of Pb²⁺ based on quaternary ammonium salt of 9,10-distyrylanthracene with aggregation-induced emission (AIE) property was developed through Pb²⁺-induced allosteric G-quadruplex (G4). The method is simple, easy to operate, cost-effective, and provides good sensitivity and selectivity.
