Abstract
Fluorescent probes for silver ion detection include organic, water-soluble compounds having aggregation-induced emission (AIE) characteristics. The probes can sense or detect silver ions through aggregation or a precipitation reaction between the silver ions and the organic compounds which induces fluorescence. The compounds are acidic, soluble in aqueous phase, and provide low background fluorescence in aqueous solutions.
