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.
A New Piezochromic Fluorescence and Aggregation-Induced Emission Compound Containing Tetraphenylethylene and Triphenylamine Moieties with Morphology-alterable Property
A novel piezochromic fluorescent (PCF) compound with aggregation-inducedemission (AIE) effect and morphology-alterable emission property was developed. The amorphous and crystalline aggregates were obtained, and their spectroscopic properties and morphological structures were reversibly and repeatedly exhibited upon pressing (fuming) or annealing. The piezochromic fluorescent nature was generated

Three tetraphenylethene-based compounds with different substituents were successfully synthesized. All these fluorescent molecules exhibited typical aggregation-induced emission (AIE) effect. In addition, these luminogens showed various mechanochromic luminescence phenomena. Moreover, the mechanofluorochromic behavior of luminogen 1 was self-reversible.
