合成了一种新型吡啶型热致性离子液晶材料n-乙基-4-（5-烷基-1,3-氧代-2-基）溴化吡啶8。这些化合物在包括室温（例如8c: G - 30sa 21 I）在内的很宽范围内表现为近晶a相。
New pyridinium type thermotropic ionic liquid crystal materials having a 1,3-oxathiane ring in the central core,N-ethyl-4-(5-alkyl-1,3-oxathian-2-yl)pyridinium bromides 8, were synthesized. These compounds exhibited a smectic A phase over a very wide range including room temperature (for example 8c: G –30 SA 21 I).
