摘要
以4-羟基苯乙烯基吡啶为质子受体,以对烷氧基苯甲酸为质子供体,制备了几种苯乙烯基吡啶类氢键型液晶。利用IR和1H-NMR检测了各中间体。POM和DSC的结果表明,两种该氢键复合物呈现明显的向列相液晶态,IR结果证明了羧基和吡啶环间分子间氢键代替了羧基间的分子间氢键。
A series of intermolecular hydrogen bonded liquid crystals between 4-（p-hydroxystyryl） pyridine and 4 （p-alkyloxy） benzoic acid were prepared. All the intermediates were investigated by IR and 1H NMtC Complexes were in vestigated by polarizing microscopy, IR and DSC. Polarizing microscopy and DSC showed that 2 of these complexes exhibi ted liquid crystals phases. IR showed the form of the intermolecular hydrogen bonding.
