Twenty new complexes were achieved based on Schiff base ligands, transition metals and rare earth. The structure and luminescence of the metal complexes were researched. The thesis is divided into three chapters to discuss.Chapter one is a basic introduction. Structures and luminescence metal fluorescence properties of Schiff base with 4f metals or 3d-4f metals were introduced. Structures and luminescence of 4f-4f mixed lanthanides were referred. Luminescence complexes with Schiff base electrostatic spinning of synthetic one dimensional nano fluorescent material, introduce the electrostatic spinning mechanism and influence factors finally discusses the application of nanomaterials.Heteronuclear Zn2Ln2 clusters {Zn2L2}{(Ln(hfac)3)2}(H2L = N,N’-bis(salicylidene)-3, 6-dioxa-1,8-diaminooctane), hfac = hexafluoroacetylacetonate) have been synthesized. All the metal complexes had been characterized by elemental analysis, IR, UV, TG and X-ray crystallography. And we discussed the 3d-4f mixed rare earth complexes regulating fluorescent properties of white light materials.Seven complexes introduced, which were obtained with the ligand(H2L) and lanthanide salts. All the metal complexes had been characterized by elemental analysis, IR, UV, TG and X-ray crystallography. Discusses the luminescence and near-infrared analysis of the complexes. The polymer electrospinning parameters tested, and successfully made into nano-fibrous material, by scanning microscopy and transmission microscopy fiber observational study due to the material properties of fiber appearance.
