of the series of 1 (starting with an n-Bu derivative) are turned into liquid crystals upon melting; no significant differences between racemic and non-racemic samples were found. Only enantiopure methyl-, n-butyl, n-pentyl, n-hexyl, and n-heptyl substituted 1 were able to form supramolecular gels in hydrocarbon solvents; all racemic ethers 1 did not show such ability.
合成了一系列对映纯和外消旋对烷基苯甘油醚1a - k。开发了一种新的,灵敏的,图形的固体对映体纯和外消旋样品红外光谱比较的方法,以获得有关这些化合物的结晶类型的初步信息。为了检测手性固相组织中的细微差异,一种新的易于实施的方法是基于色谱法,该方法测量单一溶液中对映体的相对丰度,该溶液与任意(0
