A novel Zn(II) coordination compound exhibits selective and sensitive detection of Fe3+ and acetylacetone

Pyridine derivatives have strong coordination ability, tunable electronic, optical properties and excellent stability as ligands. Their substituent engineering and conjugation extension provides an ideal platform for the construction of efficient fluorescent probes, catalysts and biological functional materials. Based on this, a new coordination compound [Zn(phen)(L)(H2O)]?4H2O was synthesized under solvothermal conditions used 1,10-phenanthroline (phen), 3-carboxy-1-carboxymethyl-2-oxidopyridinium (H2L) and Zn(?). The crystal structure and composition of the coordination compound were confirmed by single crystal X-ray diffraction and thermogravimetric analysis. Structural analysis confirmed by single crystal X-ray diffraction reveals its unique coordination geometry. In addition, it exhibits significant luminescence, making it a candidate for sensing applications. The luminescence and sensing properties of the coordination compound were investigated in detail. The Ksv values for the detection of Fe3+ and acac were found to be 3.29?105 and 6.67?105 M-1, which confirmed high and efficient sensing ability of the synthesized sensor.
