Abstract
While a single pillar[6]arene ring, nestling between two cucurbit[6]uril rings in a series of three hetero[4]rotaxanes, is conformationally mobile in solution, it adopts the energetically most favourable conformation with local C3V symmetry in the solid state.
摘要
在一系列三个杂[4]轮烷中，单个柱[6]芳烃环夹在两个葫芦[6]脲环之间，在溶液中构象可移动，但在固态时采用能量上最有利的具有局部C3V对称性的构象。
