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

点击翻译按钮获取中文摘要

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.
