Synthesis, Spectral Properties of Di-(2-methyl-8-hydroxyquinoline)Zinc

Abstract:

The complex of di-(2-methyl-8-hydroxyquinoline) zinc (Zn (2-mq)₂) was synthesized. The complex was characterized by elemental analysis, ¹HNMR, ¹³CNMR, infrared, UV-vis, XRD and molar conductivity. The zinc (II) ion was found to coordinate to the oxygen atom of phenolic hydroxyl and nitrogen atoms of 2-methyl-8-hydroxyquinoline and the complex conformes to 1:2 metal-to-ligand stoichiometry. The fluorescence properties of the complex in solid and solution were studied. The complex exhibits yellow light under the excitation of UV light. The solvent factors influencing the fluorescent intensity are discussed.
