| In this paper, through changing the ligand, the ratio of raw material, pH and other reaction conditions, 15 new compounds were synthesized, containing supramolecular complex, rare earth metal complexes and polymers. The new compounds demonstrate zero to 3 D space structures. The corresponding optimal synthetic conditions were explored, and the new compounds'crystals were obtained. Through the infrared spectra, X-ray diffraction, elemental analysis, single crystal, NMR and UV absorption spectra and fluorescence spectra, we got the structure characterization and luminous property.With the league alpha-naphthol, 1,10-phenanthroline(phen), a new supramolecular compound (C20O2H14)(C12N2H8) (supramolecular 1) were got. Selecting ligands with high coordination ability, such as 1,10-phenanthroline and acetic acid, a complex Eu2(CH3CO2)6(C12H8N2)2 (complex 2) were obtained. Selecting more ligands with aromatic ring, 2,6-pyridine-dicarboxylic acid(PDA), 1,10-phenanthroline(phen), 4,4'-diamino biphenyl(BZD), to design the reaction, five isomorphic complexes Ln(H2O)2(phen)2(PDA)(bzd)0.5(NO3)·4H2O (Ln= Nd,Sm,Gd,Tb and Dy) (complexes 37) and two cases of Ce-metal complexes Ce4(C8H3O4N)4(C8H4O4N)4(H2O)8·9H2O (complex 8), Ce(C8H4O4N)3(DMF)·4H2O (complex 9) were synthesized. Selecting the 2,4'-biphenyl acid (H2da) containing double loop structure as the main ligand, we synthesized five cases of polymers: [Eu(da)(Hda)(H2O)]n, [Eu(da)(DMF)(NO3)]n, [Eu2(da)2(OH)(NO3)(H2O)3]n, {[Eu2(da)2(DMF)2(DPA)(H2O)2]·2H2O}n, {[Gd2(da)2(DMF)2(DPA)(H2O)2]·2H2O}n (polymer 10 polymer 14). Selecting the ligand containing N, O aromas and ring organic, benzimidazole-5, 6-carboxylic acid, we synthesized one novel polymer {[Eu(C9H4N2O2)2(H2O)]·H2O}n (polymer 15).Through the test of characterization, we got the structural characterization of new compounds. Supramolecular 1 and complexes 29 exhibit zero dimension space structure. Polymers 1015 exhibit two or three dimension space structure through the different coordination of the ligands. Supramolecular 1, complexes 29 and 2-D polymers form to stable three-dimensional structure through the hydrogen bonding and the coordination effect ofπ-π.The luminous property and fluorescence life test showed that, these new compounds present good fluorescence performance, such as complexe 6 can launch green fluorescent, polymers containing Eu, launch red fluorescent. |
