| By using N-containing carboxylate ligand,S-containing carboxylate ligand and N-heterocycles ligand reacting with transition metal ions and alkli-earth metal ions under solvothermal conditions,eight metal organic complexes with different structures?1D,2D,3D?were synthesized.Their crystal structures were analyzed by X-ray single crystal diffraction,and were further characterized by elemental analysis,FTIR,UV-Vis,TGA,PXRD.The photoluminescence,small molecule sensing and adsorption for some complexes were also measured.1.Four metal organic complexes,[Mn?cptpy??1,4-Hbdc??H2O?·H2O]n?1?,[Cu?cptpy??1,4-bdc?·DMF·H2O]n?2?,[Cu?cptpy?2Cl·H2O]n?3?and [Cd?cptpy?2·H2O]n?4?with 1D structure was synthesized by 4?-?4-carboxyphenyl?-2,2?:6?,2?-terpyridine?Hcptpy?and 1,4-benzene dicarboxylic acid?H2bdc?,succinic acid?H2suc?reacting with transition metal salt[Mn?ClO4?2·6H2O,Cu?ClO4?2·6H2O,CuCl2·2H2O,Cd?ClO4?2·6H2O]under solvothermal conditions.Their structures and properties were further studied.2.Two metal organic complexes[Ca?tdc??DMF?2]n?5?,[Ba?tdc?]n?6?with 2D,3D structure were synthesized by thiophene-2,5-dicarboxylate?H2tdc?and alkaline-earth metal salt?CaCl2·4H2O,BaBr2·2H2O?under solvothermal conditions.The fluorescence properties of the two complexes were also studied.3.Two metal organic complexes[Co?bib??Hobba?2]n?7?,[Mn3?obba?3?bib? ?DMF??H2O?·DMF]n?8?with 1D,3D structure were synthesized by N-heterocycle ligand?bib?,carboxylic acid ligands?H2obba?and transition metal salt[Co?ClO4?2·6H2O,Mn?ClO4?2·6H2O]under solvothermal conditions.Complex 8 can selectively recognize the organic solvent?Tolune?after modifying by Tb3+and adsorb the organic dye Congo red. |
