counterparts. The liquid crystalline properties of the nicotinic acid derivatives, the polymers and their complexes were investigated by DSC and POM. Methylene spacers present at the terminal position of the nicotinic acid derivatives played a key role in mesophase arrangements. The columnar phase exhibited by the nicotinic acid derivatives completely disappeared in the H-bonded complexes to afford a nematic
超分子侧链液晶聚丙烯酸酯是通过分子间互补氢键的形成自组装H键供体和受体配合物而制备的。聚[4-(间丙烯酰氧基烷氧基)苯甲酸] [ m = 6(P1)和8(P2)]用作聚合物组分。液晶烟酸衍生物(C1,C2,C3和C4)用作互补的H键供体/受体对应物。通过DSC和POM研究了烟酸衍生物,聚合物及其配合物的液晶性质。存在于烟酸衍生物末端的亚甲基间隔基在中间相排列中起关键作用。烟酸衍生物显示的柱状相在H键结合的配合物中完全消失,从而提供向列相,从而证实了配合物的形成。
