| Catalytic chemical industry of the chemical industry is one of the themes of eternity. In general, catalytic material in catalytic technology are the main components of the catalyst, and has an excellent catalytic performance of catalytic materials except the application of chemical industry with more molecular siecves, metallocene, biological catalysts, as well as industrial applications and are being vigorously developed catalytic material:heteropoly acid and amorphous allou, more new features continuous catalytic material and the emergene of rapid development, such as, nano-materials, inorganic and organic composite materials. In recent years, with coordination chemistry is developing rapidly from inorganic metals and organic ligands derived from functional materials to build a complex, because in the materials design and synthesis and function of different pore compound with inorganic or organic material unique strengths and development space, thereby making it a class with a strong potential for development of inorganic and organic composite materials and concern in the international arena. In this paper, the work of select transitional metal ions and organic ligands- dicarboxlylates, using principles of molecular assembly to build the target functional complexes and, respectively, for their synthesis methods, crystal structure and the nature of the analysis, focus on the functional complexes as a catalyst-sensitized nano-TiO2 photocatalytic degradation of performance, this article is divided into three parts:Firstly, an over view of the functional complexes of the basic concepts, research, application profiles, as well as its catalytic at the development of the field, and type dicarboxylates ligand functionality to build complex research progress on the wrap-up.Secondly, we separately select Azobenzene-3,3'-dicarboxylic Acid (H2AZDB),Azobenzene-4,4'-dicarboxylic Acid (H2ADB) and 2-2'-Bipyridcline-4,4'-dicarboxylic acid (H2bpdc) as the basic building units, metal ions as the central ion, assembly synthesized 14 new functional complexes from 1D to 3D: [Ag2(AZDB)(bipy)]·0.5H2O(1),[Co(AZDB)(bipy)0.5](2), [Ag2(AZDB)(bpe)]·H2O(3), [Co2(AZDB)2(bpe)2](4), [Ni2(AZDB)2 (bpe)2](5), [Ag(bpp)]·(AZDB)(H2O)3(6), [Co2(AZDB)2(bpp)2](7), [Mn(ADB)(phen) (H2O)2](8), [Cd3(ADB)3(phen)3]·4H2O(9), Zn(ADB)(H2O)(10), [Co(dcbp)(H2O)3](11), [Zn(dcbp)(H2O)3]·3H2O(12), [Ni(dcbp)(H2O)2](13), {[Dy2(bpdc)3(H2O)3]·H2O}n(14). The 14 complexes have been determined by the X-ray single crystal diffraction analysis, and IR spectra, thermal analyses, cyclic voltammograms and fluorescence were used to investigate their spectroscopy characters and properties.Finally, we synthesized the Nano-TiO2 via sol-gel method, then we got the nano-complex-sensitized TiO2 photocatalytic materials through a composite of the above-mentioned coordination polymers with nano-TiO2. Choose Rhodamine and Congo red as the target pollutants studied complexes sensitized nano-TiO2 photocatalytic degradation of performance. By analyzing the alone-mentioned structural characteristics of the study sensitized structural characteristics of the study sensitized TiO2 photocatalytic properties before and after diffenences, finally received some regularity conclusions. |
