Research On Polyoxometalate-based Organic-lnorganic Hybrid Materials

Based on the investigations of trCmendous literatUres, WO find that organic-inorganic hybridmaerials, which are vital varieties of material science, are fertile field and have attractive aPpliedvalues. Upon that, this treatise falls tO doing works running after this hot point.Four chaPters are comPrised in this thesis:ChaPterl: gives the outline of organic-inorganic hybrid materiaIs area. Thrugh investigationand generalization, We know that polyoxometalate-based orgaic-inorganic hybridmaterials,which have so various smictures as to design and tailer molecules easily,have both functional properties of orsanic moieties and therml stabilization ofinorganic moieties.ChaPter 2: introduces synthesis methods of a serial of organic-ino4anic hybridpolyoxometalates. Then, emPloying IR SPecmim, elemental analysis and TGA, we givethis seria1 of comPounds necessny detennnations. Eighteen comPounds have beensynthesised in thes thesis, among which seven comPounds are objectS. In this chaPtef,we obtain tliree opl smictUres of corresPonding comPounds and conclude throughcomParison that plane proPerty goes bad with length of substitutes attaching to thecations.ChaPer 3: has systendic studies of OPticaI propenies of this seriaI comPounds. Such measaresas elecbe SPetri, fluorescence sPectruIn in solution and in solid, two-Photonabsorphon, oPhcal lindting are emPloyed in these studies. We find that all of thesecomPounds have ligh-excited emitting properies and non-linear absorphon propertiesat different eXtents. All of this properties lay out aPplied prospects of them in opt-eIectron funchonal materials area.ChaPter 4: Nugh determinations of cyclic voltarnmetry and diff pulse voltammetry theirelectrochemical properties are studied. We find that each of them haS niceelectrochemical properties and reversible redox properties. Whereaftef, we obtain somebeneficiaI conclusions via comParison and analysis.In a word, this treatise exPands its sight in extensive area, emPloys organic-inorganic sthetegy.We have acquired a serial of comPounds with scientific and aPplying values, which give novel andbeneficial groping to the research of organic-inorganic hybrid maerials.
