制备了多种同系1-脱氧-1-（N-甲基烷氨基）-D-葡萄糖醇，并对其液晶相进行了表征。在这项研究中，这些材料的热致液晶性能进行了研究。所形成的中间相被证明是近晶A类与叉指型双层有序的组成分子。这种排序被认为是通过相邻碳水化合物部分之间的氢键来稳定的。这些材料的性质进行了比较与其他密切相关的非环状碳水化合物。
A variety of homologous 1-deoxy-1-(N-methylalkamido)-D-glucitols were prepared and their liquid crystal phases characterized. In this study the thermotropic liquid-crystalline properties of these materials are investigated. The mesophases formed are shown to be of the smectic A class with an interdigitated bilayer ordering of the constituent molecules. This ordering is thought to be stabilized by hydrogen-bonding between neighbouring carbohydrate moieties. The properties of these materials are compared with those of other closely related acyclic carbohydrates.
