| The triazine-carboxylate ligands used as the expending of1,3,5-benzenetricarboxylateown excellent coordination ability. And the complexes coordinated with transition metals andlanthanide metals posses widely application in gas storage, segregate, catalysis, magnetic andfunctional materials, etc. Furthermore, this kind of complexes exhibit high thermal stabilityand good luminescent properties. Thus, the synthesis, structure and functional propertiesresearch of triazine-carboxylate ligands and complexes will be attracting more and moreattention.In this thesis, we used cyanuric chloride and p-aminobenzoic acid as raw materials,synthesized two compounds4,4’,4’’-((1,3,5-triazine-2,4,6-triyl)tris(azanediyl))tribenzoic acid(L1) and4,4’-((5-chloro-1,3-phenylene)bis(azanediyl))dibenzoic acid (L2) and then usingthem as ligands to synthesize two new complexes with transition metals of Zinc and Copper.In addition, in the work other11transition metals complexes were also synthesized firstlywith1,3,5-benzenetricarboxylate,4-(I)pyrazole,4,4’-bipyridine ligands etc. respectively. Allcomplexes were characterized by elemental analysis, IR spectroscopy, UV spectroscopy,X ray single-crystal and powder diffraction. Therein, complexes14and713were alsocharacterized by thermogravimetric analysis and complexes14,5,7were characterized byfluorescence spectroscopy. Furthermore, the stabilities, charge and Wiberg bond indexdistribution of two complexes5and6were calculated by quantum chemistry. |
