Preparation and Characterization of New Dimensional Polymers by Fixation of Molecular Arrangement in Ionic Molecular Crystals

离子分子晶体是由具有平面或四面体结构的三元或四元阴离子分子与阳离子分子结合而成。然后，在固体状态下，将羧酸苄基吡啶的离子相互作用热转化为苄基酯的共价键。产物聚合物应具有规则的网络结构。制备了多种单体并对其进行了测试。其中大多数是无定形聚合物，但也有一些交联型结晶聚合物，例如，从四主题膦碱衍生物的组合中得到的。

Ionic molecular crystals were prepared by the combinations of tri- or tetra-topic anionic molecules with cationic ones, both of which had planar or tetrahedral structures. Then, in the solid state, the ionic interactions of benzylpyridinium carboxylate were thermally transformed to covalent bonds of benzylester. The product polymers were expected to have the regular network structures. A variety of monomers were prepared and examined. Most of them gave amorphous polymers, but some cross-linked crystalline polymers were obtained, for example, from the combination of tetra-topic phorphyrine derivatives.
