吡啶类液晶具有粘度低、S相温宽等特点，在混合液晶配方中加入该类液晶能有效地改变混合液晶材料许多电光性能，如降低阀值电压、缩短响应时间、增加低温稳定性等，因此在一些TN和FLC液晶材料中经常会见到吡啶类液晶的配方组成。
本论文合成了氢键受体3,5-二（4-吡啶甲酸）甲苯二酯，和带吡啶官能团的聚乙烯醇侧链液晶高分子。选用聚乙烯醇作为主链，苯乙烯吡啶作为液晶基元，合成了聚乙烯醇侧链液晶高分子。同时，利用分子间氢键自组装合成的侧链液晶高分子的低熔点使它克服了热致性液晶的相转变温度较高难以加工的不足。最后采用红外光谱（FT-IR）对所合成的液晶单体与液晶聚合物的结构进行了表征，采用差示扫描量热分析（DSC）、热失重分析（TGA）、偏光显微分析（POM）等研究方法对它们的液晶性能及热稳定性进行了表征。
英文翻译如下：
Pyridine LCD with low viscosity, S-wide, and other characteristics of the mixed formula in the LCD to join such LCD can effectively change the mix liquid crystal electro-optical properties of many materials, such as lower threshold voltage, shorten response time, increase low-temperature stability , And in some FLC、TN、LCD materials often see the pyridine LCD formula.
We have prepared a proton donor-3,5-bis （4-pyridine carboxylic acid）methylbenzene diester，and a band of pyridine functional group of polyvinyl alcohol liquid crystal polymer side chain. Selection of polyvinyl alcohol as a main chain, styrene pyridine a

The pyridine class liquid crystal has the viscosity lowly, characteristics and so on S warm width, joins this kind of liquid crystal in the mix liquid crystal formula to be able effectively to change the mix liquid crystal material many electric light performance, like reduces the valve value voltage, the reduction response time, increases the low temperature stably and so on, therefore can see the pyridine class liquid crystal frequently in some TN and in the FLC liquid crystal material the formula composition. The present paper synthesized the hydrogen bond acceptor 3,5- two (4- pyridine.carboxylic acid) the toluene two ester, with belt pyridine functional group polyvinyl alcohol side chain liquid crystal high polymer.Selects the polyvinyl alcohol to take the principal chain, the styrene pyridine took the liquid crystal element, synthesized the polyvinyl alcohol side chain liquid crystal high polymer.At the same time, used the intermolecular hydrogen bond to cause it from the asse
