　　Summary:
　　Schiff bases ligands and their metal complexes not only in analytical chemistry, catalysis, etc. There are a wide range of uses, and medicine, biochemistry and photochromic area also has important research value, this paper reported the pyrazolone class of Schiff base Neodymium Magnets and its metal complexes synthesis, characterization and properties were determined. This paper consists of the following components:
　　The first chapter briefly describes the mechanism of Schiff base condensation, Schiff base ligands and their metal complexes research and explore the structure of DNA and metal complexes with DNA.
　　Chapter to Chapter, introduced the 1 - phenyl-3 - methyl -5 - hydroxy-pyrazole-4 - formaldehyde (benzoyl) hydrazone ligand (H2L1), 1 - phenyl-3 - A -5 - hydroxy pyrazole-4 - formaldehyde (salicylic acid) hydrazone ligand (H3L2), 1 - phenyl-3 - methyl -5 - hydroxy-pyrazole-4 - formaldehyde (isonicotinoyl) hydrazone ligand (H2L3), 1 - phenyl-3 - methyl -5 - hydroxy-pyrazole-4 - formaldehyde (hydroxy benzoyl) hydrazone ligand (H3L4) and rare earth metal complexes are synthesized and characterized by elemental analysis, metal content titration, http://www.everbeenmagnet.com/en/products/110-sintered-neodymium-magnets molar conductance analysis, IR, NMR and other means of characterization; has explored these ligands and rare earth metal complexes with DNA.
　　Chapter VI, fluorescence spectra, UV - visible spectra of 1 - phenyl-3 - methyl -5 - hydroxy-pyrazole-4 - formaldehyde (benzoyl) hydrazone cation selectivity of the different results show that the compound of Cu2 has a good selectivity, but also train the [Cu · HL1 · DMF · ClO4] crystal shows a better ligand for the coordination of copper ions.
