为了通过非共价相互作用构建介晶夹套液晶聚合物，聚(2-乙烯基苯-1,4-二酸)和五系列吡啶衍生物分别作为氢键供体和受体被合成。化合物的结构通过1H NMR、FT-IR、凝胶渗透色谱进行了确证。通过氢键供体和受体的混合得到一系列具有相同聚合度和多分散性的配合物。通过 FT-IR 光谱证实了氢键。我们发现吡啶衍生物的刚性和结构以及氢键的强度都会影响所得配合物的液晶行为。复合物 PPANCx 和 PPANNEC 中分别观察到近晶 A 相和柱状向列相。
In an attempt to construct mesogen-jacketed liquid crystalline polymers through noncovalent interactions, poly(2-vinylbenzene-1,4-dioic acid) and five series of pyridine derivatives were synthesized as hydrogen-bonding donor and acceptors, respectively. The structures of the compounds were confirmed by 1H NMR, FT-IR, and gel permeation chromatography. A series of complexes with the same degree of polymerization and polydispersity were obtained by mixing the hydrogen-bonding donor and acceptors. The hydrogen-bonds were confirmed by FT-IR spectra. We found that the rigidity and structures of pyridine derivatives and the strength of the hydrogen-bonding all influenced the liquid crystalline behaviors of the resulting complexes. Smectic A and columnar nematic phases were observed in complexes PPANCx and PPANNEC, respectively.
