| In the first chapter, the concepts of coordination polymers, the histories and new developments of bis(imidazole) ligands are concisely introduced. At the end of this chapter, we pointed out the importance of the search project and summarized the important results obtained in the thesis.In the second chapter, six new coordination polymers, namely [Zn1.5(BTC)(obib)(H2O)2]·1.5H2O (1), [Zn3(BTC)2(mbib)3] (2), [Zn)3(BTC))2(bbi)1.5(H2O)]·H2O (3), [Co6(BTC)4(obib)6(H2O)3]·9H2O (4), [Co1.5(BTC)(mbib)1.5]·0.25H2O (5), and [Co4(BTC)2(bbi)2(OH)2(H2O)]·4.5H2O (6), where obib = 1,2-bis(imidazol-1-ylmethyl)benzene, mbib = 1,3-bis(imidazol-1-ylmethyl)benzene, bbi = 1,1'-(1,4-butanediyl)bis(imidazole), and BTC = 1, 3, 5-benzenetricarboxylate anion, were synthesized under hydrothermal conditions. In 1-6, each of obib, mbib and bbi serves as a bidentate bridging ligand. In 1, BTC anions act as tridentate ligands, and compound 1 shows a 2D polymeric structure which consists of 2-fold interpenetrating (6,3) networks. In compound 2, BTC anions coordinate to zinc cations as tridentate ligands to form a net with (64·82)2(86)(62·8)2 topology. In compound 3, BTC anions act as tetradentate ligands, and coordinate to zinc cations to form a net with (4·62·83)2(8·102)(4·6·83·10)2 topology. In compound 5, each BTC anion coordinates to three Co cations, and the framework of 5 can be simplified as (64·82)2(62·82·102)(63)2 topology. For 4 and 6, the 2D cobalt-BTC layers are linked by bisimidazole ligands to form 3D frameworks. In 6, the Co centers are connected byμ3-OH and carboxylate O atoms to form two kinds of cobalt-oxygen clusters. Thermogravimetric analyses (TGA) for these compounds are discussed. The luminescent properties for 1, 2 and 3 and magnetic properties for 4, 5 and 6 are also discussed in detail.In the third chapter, ten new coordination polymers, namely [Cu(BTCA)0.5(H2O)3]·2H2O (1), [Co2(BTCA)(H2O)5]·2H2O (2), [Ni2(BTCA)(H2O)5]·2H2O (3), [Zn(BTCA)0.5(H2O)2]·0.5H2O (4), [Mn(BTCA)0.5(bipy)(H2O)] (5), [Mn(BTCA)0.5(phen)(H2O)] (6), [Zn(BTCA)0.5(obib)]·2.5H2O (7), [Zn(BTCA)0.5(pbib)0.5]·H2O (8), [Zn(BTCA)0.5(bbi)]·H2O (9) and [Co(BTCA)0.5(bbi)]·H2O (10), where bipy = 2,2'-bipyridine, phen = 1,10-phenathroline, obib = 1,2-bis(imidazol-1-ylmethyl)benzene, pbib = 1,4-bis(imidazol-1-ylmethyl)benzene, bbi = 1,1'-(1,4-butanediyl)bis(imidazole), and BTCA = 1,2,3,4-butanetetracarboxylate anions, were synthesized. Compounds 1–3 possess 2D polymeric structures, while compound 4 has a 3D network. Compounds 5 and 6 exhibit infinite 1D chain structures, and the adjacent chains are connected throughπ-πinteractions between the aromatic rings of bipy or phen ligands. Both of the 3D frameworks of 7 and 8 are built from 2D zinc-carboxylate layers stretched by bis(imidazole) ligands. Compounds 9 and 10 are isostructural and show 3-fold interpenetratedα-Po structures. The thermal stabilities of 1–10 were studied by thermogravimetric analysis. The luminescent properties for 7–9 in the solid states, and magnetic property for 10 are also discussed in detail.In the fourth chapter, reactions of 1,1'-(1,4-butanediyl)bis(imidazole-2-phenyl) (bbip) with ZnII and CdII salts in the presence of dicarboxylic acids produce six new coordination polymers, namely [Zn(o-bdc)(bbip)]·H2O (1), [Zn(m-bdc)(bbip)]·H2O (2), [Cd(m-bdc)(bbip)] (3), [Zn(OH-bdc)(bbip)] (4), [Cd(OH-bdc)(bbip)] (5) and [Zn(fum)(bbip)]·H2O (6), where o-H2bdc = 1,2-benzenedicarboxylic acid, m-H2bdc = 1,3-benzenedicarboxylic acid, OH-H2bdc = 5-hydroxisophthalic acid and H2fum = fumaric acid. Compound 1 shows a one-dimensional double-stranded chain structure. Compounds 2 and 4 possess 2D polymeric layers, and the layers are connected through van der Waals forces and hydrogen bonds into 3D supramolecular structures, respectively. Compounds 3, 5 and 6 exhibit 3-fold interpenetrating diamondoid networks. The luminescent properties for these compounds in the solid state are discussed.The fifth chapter is the conclusions.
