Abstract

The thermal and mesophase behaviour of a mixture of 4-octylbenzoic acid and 4,4'-bipyridine is studied. The complex shows appearance of two distinct phases which otherwise are not present in any of these constituents. Polarizing optical microscopy and differential scanning calorimetry indicate that the mixture displays liquid crystalline properties. X-ray diffraction studies confirm the presence of hydrogen bonds.

4-辛基苯甲酸和4,4'-联吡啶衍生的氢键型液晶元的合成，热分析和晶体结构

摘要

研究了4-辛基苯甲酸和4,4'-联吡啶的混合物的热和中间相行为。该配合物显示出两个不同相的外观，否则在这些组分中的任何一个中都不存在。偏光光学显微镜和差示扫描量热法表明该混合物显示液晶性质。X射线衍射研究证实了氢键的存在。
