  • Title: Selective sensing of H2PO4(-) (Pi) driven by the assembly of anthryl pyridinium ligands.
    Author: Gong W, Zhang Q, Wang F, Gao B, Lin Y, Ning G.
    Journal: Org Biomol Chem; 2012 Oct 07; 10(37):7578-83. PubMed ID: 22895842.
    Abstract:
    Synthesis of a simple amidopyridinium-based sensor (F1) and its fluorescence behavior toward H(2)PO(4)(-) (Pi) were investigated. The anthryl group in F1 exhibited a strong excimer emission via Pi-directed assembly of F1; other anions showed a negligible effect. The Pi-induced assembly of F1 was rationalized by photophysical experiments and DFT calculation.
