Assembling Properties Of Aromatic Sulfonic Acid And Lead Coordination Polymers

In this thesis, reaction of seven arenesulfonic acids, auxiliary N-heterocyclicmolecules and different lead salts result in230-D,1-D,2-D and3-D lead sulfonatecomplexes, which are characterized by elemental analyses, PL, IR, TG and singlecrystal X-ray diffraction. Structure analyses indicate that the introduction of thehydroxyl groups can enrich the coordination modes of the sulfonate group and improvethe coordination ability of sulfonate groups to lead(II) cations, thus generatinghigh-dimensional coordination polymers. Meanwhile, the different structures of ligandsand introduction of N-heterocyclic molecules play important role on the architectures.In the Pb-monosulfonate complexes, the coordination of chelating N-heterocyclicmolecules effectively limit the extension of structures. In comparison, disulfonatespossess abundant coordination modes, which are easy to construct layer structuredespite of the coordination of N-heterocyclic molecules to lead(II) cation. Thesulfonates with carboxyl and hydroxyl grous are more easier to constructhigh-dimensional structures. However, most of the complexes exhibit chain structureowing to the existence of coordinated water molecules. Moreover, some of the leadsulfonate complexes exhibit luminescent emission in aqueous solution.
