摘　　要：Schiff base pyridine zinc(II)complexes 1~4 were synthesized by the reaction of the 2-((2-hydroxybenzylidene)amino)phenol Schiff base with appended donor functionality,zinc acetate,and pyridine.The results of the structural characterization of the complex show that they have the same coordination mode and similar steric structure.Complexes 1 and 3 form a one-dimensional chain structure and two-dimensional grid struc-ture by lots of hydrogen bonds,respectively.Thermogravimetric analysis shows complexes 1~4 can exist stably be-low 150℃.The results of the fluorescence quenching experiments between the complexes and DNA-EB show that the interaction between them is intercalation,and the effect of complex 1 is the most obvious.It is speculated that the steric hindrance of complex 1 is relatively small,and the aromatic ring on the ligand is more likely to inserted into the base pair of DNA.
