| Because of the characteristics with good optical, electrical, magnetic, fluorene and its derivatives was widely used in research in the fields of agriculture, medicine,optoelectronic materials. Due to the structural diversities and wide applications, the metal organic complexes, synthesized by metal and organic carboxylic acid, have attracted more and more attention and research. But the study on carboxylic acid of fluorene as the main ligand of metal complexes is not too much. This thesis is to synthesize a series of complexes with transition metal and carboxylic acid of fluorene as the main ligands, and study on its structure and performances.Carboxylic acid of fluorene,(Fluorene-9,9-diyl)dipropanoic Acid, as main ligand(H2L1), synergizing 1, 4-bis(imidazole)butane(L2) and 1,10-phenanthroline(L3) as ancillary ligands, coorperated with metal ions Cu2+, CO2+ and Zn2+, synthesized seven new metal complexes which are unreported in the literature, and developed their crystal structures. The seven new coordination compounds are Cu2(L1)2(H2O)2·2ET(1), Cu2(L1)2(DMF)2·DMF(2), Cu(L1)(L3)(MT)(3),Co(L11)2(L2)·2HL11·3H2O(4), Co(HL1)2(L2)·2H2O(5), Zn(L1)(L2)(6) and Zn(L1)(L2)·ET(7). The seven complexes were characterized by means of elemental analysis, infrared spectroscopy and X- single crystal diffraction, and their crystal structures were analyzed in detail. The effects of different synthesis methods, solvents and pH environment on coordination modes and spatial structure were discussed. The thermal stability and fluorescence properties of the complexes were analyzed by means of thermal weight and fluorescence spectra, and the reasons for the changes of the thermal stability and fluorescence properties of the complexes were also studied by means of differences of the complexes structures. These researches have important significance for the further design of metal complexes with better performance. |
