Luminescent Materials And Its Ion-Recognition Effects Based On The N/S Heterocyclic Carboxylic Acid

It is an inevitable trend to analysis of the advantages, which the use of scientific research in other disciplines to solve scientific problems is the interdisciplinary integration. In recent years, the application of coordination materials with kinds of properties has been more active, this trend is justified by the advantages of both inorganic and organic optical materials. In the thesis, tweleve coordination materials based on nitrogen- or sulfur- heterocyclic ligands were designed and constructed by hydrothermal methods. The works are summarized as follows:Firstly, over view of the functional materials of the basic profiles, the research progress on the wrap-up. As well as elaborated the application in luminescence and recognition.Secondly, with 3-thiophene carboxylic acid ligands synthesized three coordination polymer materials, [Zn(Tma)(bpy)(H2O)]·2H2O(1), [Co3(Taa)4(bpy)4]·2ClO4·bpy·2H2O (2), [Cd(Taa)2(dpp)(H2O)]n (3), such as its crystal structure and fluorescence properties were analyzed. On this basis, we mensurated the ion-recognition of functional materials 2 and 3, found that 2 have a good recognition effect for Ag +. Thirdly, five metal–organic materials based on 2-propgl-1H-imidazole4,5-dicarboxy Acid (H3pimdc) had synthesized and studied: [Cd(H2pimdc)2]n (4), [Cd2(Hpimdc)2(bpp)(H2O)]n (5), [Cd2(Hpimdc)2(bbi)0.5(H2O)2]n (6), [Pb(H2pimdc)2(H2O)2]n (7), [Zn(Hpimdc)(H2O)]n (8). We have investigated their IR, TG and fluorescence properties.Fourthly, we select another nitrogen- heterocyclic complex as the basic building units, assembly synthesized 4 new functional materials: two-dimensional or three-dimensional materials with many different helical structure: [Cd(bbi)2Cl2]n (9), [Cu(btb)2(H2O)2]·2NO3 (11), three-dimensional embedded coordinate materials [Cd2(Naphdc)2(bbi)(H2O)]n (10), two-dimensional materials with hanging arm: [Cu(btdc)2)]n·H2O (12), investigated their Crystal structures, IR, TG and fluorescence properties.Finally, conclude a brief summary and viewed the outlook of this work. [H2Tma=3-thiophenemalonic Acid, Htaa=thiophene-3-acetic acid, H3pimdc=2-propgl-1H-imidazole4,5-dicarboxy Acid, H2Naphdc= Naphthalene-1,4-dicarboxylic acid, H2btdc=1-Benzyl-1,2,3-triazole-4,5-dicarboxylic acid, bbi=1,1′-(1,4-butanediyl)bis(imidaz-ole), dpp=1,3-Di(4-pyridyl)propane, btb=1,4-Bis(triazol)butane, bpy=bipyridine ]...
