Selective sensing of H2PO4(-) (Pi) driven by the assembly of anthryl pyridinium ligands.
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.
