一系列氢键诱导液晶复合物的合成及表征

Preparation and Characterization of a Series of Intermolecular Hydrogen Bonded Liquid Crystalline Complexes

以2-氰基-3-［4－（2-氯3-甲基-1-丁酰氧基）」-苯基丙烯酸（A）为质子给体、N－（4-吡啶基亚甲基）－4-烷氧基苯胺（nSSZ）为质子受体，合成了一系列新的氢键复和物．经红外光谱证实了分子间氢键的存在．通过DSC、偏光方法及X射线衍射方法对其液晶行为进行研究．结果表明复合物呈现近品相行为．

A series of intermolecular hydrogen bonded liquid crystals between 2-cyano-3-[4(2-chloro-3-methyl-l-butanoy- acrylic acid (A) and N- (4-pyridylmethylidene)anilines(nSSZ) were prepared and investigated by DSC, polarizing microscopy and X-raydiffraction. The results showed that these complexes exhibited smectic A phases.
