Synthesis of ion thermal rise in recent years a new synthetic method, hydrothermal / solvothermal Because the ion thermal environment is different from, the ionic liquid in the synthesis process can also play the role of the reactants, the solvent, the structure-directing agent, can often be obtain novel structure of difficult or can not be obtained in other synthesis conditions. In this paper, a novel metal coordination polymers ion heat Synthesis structure and in-depth study of the structure and nature. Work in the following three systems: a rare earth naphtalate coordination polymer: the Hmim] [as Ln2Cl (1,4-the NDC) 3] (Ln = Y (1), La (2), Ce (3 ), Pr (4), Nd (5), Sm (6), Eu (7), Gd (8), Tb (9), Dy (10), Ho (11), Er (12)), [Pmim ] [Ln2Cl (1,4-NDC) 3] (Ln = Pr (13), Eu (14); Hmim = 1 - hexyl 3 - methylimidazolium Pmim = 1 - pentyl-3 - methyl imidazole ,1,4-NDCH2 = 1,4 - naphthalate). Second, trimellitic acid, of the transition metal coordination polymer: [Hmim] 2 [TM (TMAH) 2 (H2O) 2] (TM = Co (15), Ni (16), Mn (17); Hmim = 1 - -3 - methyl-imidazole, TMAH3 = 1,3,5 - benzene tricarboxylic acid). Third, transition metal naphtalate coordination polymer: [emim] [CdBr (1,4-the NDC)] (18), [emim] [CDI (1,4-the NDC)] (19) [Emim] [ ZnBr (1,4-the NDC)] (20), [Emim] CoBr (1,4-the NDC)] (21) (Emim = 1 - ethyl-3 - methyl-imidazol-,1,4-NDCH2 = 1] , 4 - naphthalene dicarboxylic acid). The compounds 1-14 each other isomorphism body belongs to the monoclinic P21 / c space group. Its structural characteristics of the rare earth ions and carboxylate, chloride ion coordinated to form a one-dimensional chain, each one-dimensional chain by four one-dimensional chain of 1,4 - naphthalene dicarboxylic acid bridging adjacent building into [Eu2Cl (1 4-NDC) 3] the nn-three-dimensional structure, Hmim or Pmim cations fill in the holes. This series of compounds are the first ion thermal synthesis of the the rare earth naphtalate ligand polymer. Presents rare earth compounds 5,6,7,12 characteristic emission peaks, while the emission peaks of the ligand compound 9,10 presented; magnetic studies have shown that the compound 8 showed a paramagnetic compound 9,10 showed the diamagnetic. Compounds 15-17 isomorphism body to each other, belong to the tetragonal P43212 chiral space group, which is characterized by chiral coordination polymers the Co2 ions through bidentate bridging ligand TMAH connected to form a three-dimensional open-framework structure. Contains two spiral channels, smaller pores by the right-handed helical chains adjacent large pore formed by the left-handed helical chains bypass the large pore cross-sectional size of 8.5 × 8.1? Filled Hmim cation in which the three-dimensional structure. In addition, the structure also there is a hydrogen bond. The topological analysis show that the series of compounds 6 (6) 4 connected network. Thermal stability studies show that the main skeleton of these compounds in the loss of water molecules change. The compounds 18-21 each other isomorphism body belongs to the monoclinic P21 / n space group. Its structure is characterized [m 2 x 2 (1,4-the NDC) 4] (M = Cd, Zn, Co,; X = Br, I), the structural unit of the wheel ring with the same four wheel ring structural units through 1,4-the NDC bridge Liancheng (4, 4) MX (1,4-NDC)] nn two-dimensional anion network structure, Emim cation charge balance agent located in between the layers. The thermal stability studies have shown that these compounds can be stable up to 300 oC. Fluorescence analysis showed that this series of compounds fluorescent ligand showed emission.
