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 NMR. 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.
