| The exquisite designed construction of metal-assembled and metal-cluster frameworks by use of the principles of self-assembly, especially for coordination polymers and supramolecular architectures, represents a topical and current research interest in chemistry, materials, medicals and biology areas today. As complexe molecular solid contain inorganic metal and organic ligand at the same time, so it has more advantage and developmental space in the facet of material design and functional complex, which is compared with pure inorganic and organic solid. Presently, literatures about functional complex materials mostly focus on magnetism, optics, electricity, biology, but the report about its catalytic area is still rare. In this theses, we choose O-Phenylenediacetic acid(1,2-H2pda),m-Phenylenediacetic acid(1,3-H2pda),p-Phenylenediacetic acid(1,4-H2pda), as building units and use transition metal ions as Zn, Cd metal center, meanwhile, accompany aromatic ligands including N donors. As results, 12 novel organo-matel supramolecular polymers namely {[Cd(1,4-pda)(bpb)(H2O)]·H2O}n(1) , {[Zn2(1,3-pda)2(phen)2]·4H2O}n(2) ,{[Cd2(1,3-pda)2(bpy)2]·2H2O}n(3) , {[Cd2(1,3-pda)(phen)]·2H2O}n(4) ,[Zn(1,3-pda)(bpp)]n(5) , {[Zn(1,2-pda)(phen)4]·NO3·4H2O}n(6) ,[Zn(1,2-Hpda)2(bpy)]n(7) , [Zn(1,2-pda)2(bpy)(H2O)]n(8) ,{[Cd2(1,2-pda)2(phen)3(H2O)]·EtOH·3H2O}n (9),[Cd2(1,2-pda)2(bpy)2(H2O)2]n(10) ,{[Cd2(1,2-pda)2(ip)4]·3H2O}n(11),[Cd2(1,2-pda)2(ip)4]n(12);The 12 complexes have been determined by the X-ray single crystal diffraction analysis, and IR spectra, thermal analyses were used to investigate their spectroscopy characters and properties. Finally, Nanoporous TiO2 sensitized by complex has been used for cheaking photocatalytic activity for degradation of acidic fuchsin as stimulant dyes. The results show that the 3 kinds of phenylenediacetic acids mentioned above play an important role in the construction of novel organo-metal supramolecular polymers, which could act as donor-acceptor of hydrogen bonds formulating multi-dimensional expanded networks. Meanwhile, some regular conclusion have been summarized through the comparison studies on structures, assembled rules, spectroscopy characters, fluorescence,photocatalytic activity of TiO2 sensitized by compounds of the supramolecular polymers constructed from 3 kinds of phenylenediacetic acids.
