Synthesis Of Imidazole Derivatives And Application Of Their Metal Complexes

Imidazole derivatives have been widely used in optoelectronic materials,biological simulation,catalytic synthesis and other fields because of their unique structure and good photoelectric properties and biological activity after forming complexes with metal salts.In this paper,a series of imidazole derivatives and zinc complexes were synthesized by various methods and characterized by various methods.（1）benzimidazole（BI）,2-methylbenzimidazole（MBI）,2-Phenylbenzimidazole（PBI）and imidazole-4,5-dicarboxylic acid（IDC）were successfully synthesized.The structures of the four imidazoles were characterized by elemental analysis,IR,UV and NMR.（2）Six imidazole zinc coordination compounds:ZIF-8,C₂₆N₈O₈H₂₀Zn₂·H₂O,Zn（MBI）₂（NO₃）₂,Zn（PBI）₂（NO₃）₂,C₃₆N₁₀O₁₄H₂₆Zn₂,Zn（ABI）₂（NO₃）₂,were synthesized by ultrasonic synthesis,hydrothermal synthesis and liquid phase diffusion.The structure of the complex was determined by elemental analysis,IR,UV,conductivity and XRD analysis,and its stability was studied.（3）The fluorescence properties of imidazole ligands and complexes were analyzed.Both ligands and complexes emit blue violet light.The ligand molecule belongs to the luminescence caused by intramolecular proton transfer,and the complex belongs to the luminescence of metal perturbation ligand.（4）The catalytic properties of the complexes for the formation of new fungicides from dodecylamine and acrylonitrile were studied.It was found that C₂₆N₈O₈H₂₀Zn₂·H2O and C₃₆N₁₀O₁₄H₂₆Zn₂had the best catalytic properties.
