Abstract
A novel Salamo-Salen-Salamo hybrid Mg(II) complex (sensor MT) was well-designed and synthesized for selective sensing of H2PO4ˉ ions through ICT and CHEF effects and via displacement pathways in DMSO/H2O (9:1, v/v) medium. The sensor MT exhibited a bright blue fluorescence signal (470 nm) that is quenched upon encountering H2PO4ˉ ions in a short time. The simplicity and specificity of the recognition process make it an ideal fluorescent probe for detecting H2PO4ˉ in test strip, Zebrafish, and bean sprout. Theoretical studies using UV–vis spectroscopy, HR-MS, 1H NMR titration, and theory calculations (DFT & TD-DFT) provided a better understanding of the sensing mechanisms and binding modes of the sensor MT and H2PO4ˉ. This new recognition strategy may open up new avenues for further applications in vitro, in vivo, and in plants.
