A novel series of chiral liquid crystalline tripedes Glucoside and Mannoside derivatives Gn and Mn (n=1–3) have been synthesised. The inner cores consist of methyl α‐D‐Glucoside G or methyl α‐D‐Mannoside M, regioselectively functionalised at the less hindered position C6, with tert‐butyldimethylsilyl (TBDMS), hydroxyl or carboxylic acid moieties. The cores, which can acquire several flexible conformations
已经合成了一系列新的手性液晶三足体葡糖苷和甘露糖苷衍生物G n和M n(n = 1–3)。内核由甲基α- D-葡糖苷G或甲基α- D-甘露糖苷M组成,在较低受阻位置C6区域选择性地官能化,且具有叔-丁基二甲基甲硅烷基(TBDMS),羟基或羧酸基团。可以获取多种柔性构象的核心通过柔性的己酰基间隔基连接到杆状趋于菌种的氰基联苯单元上。这些糖超分子表现出手性向列(N *)和近晶A(SmA)相。讨论了核心手性和官能团对热和介晶特性的综合影响。
