supramolecular level. In both crystal structures, solvent channels are present and differ in both shape and capacity. Furthermore, the methoxy‐substituted macrocycle undergoes a single‐crystal‐to‐single‐crystal transformation during which the molecular structure changes its conformation from 1,3‐alternate (loaded with THF/water) to 1,2‐alternate (apohost form). Molecular modelling techniques were applied to explore
基于二硒化物的动态共价化学,提出了一条合成高纯硒环[4]芳烃大环的合成途径。杯芳烃的内缘装饰有烷氧基或叔叔丁酯基团。对具有甲氧基和乙氧基取代基的两种THF溶剂的单晶X射线分析表明,它们的分子结构和超分子水平的变化具有高度相似性。在两种晶体结构中,均存在溶剂通道,并且其形状和容量均不同。此外,甲氧基取代的大环化合物经历了单晶至单晶转变,其分子结构从1,3-交替(载有THF /水)变为1,2-交替(脱辅基形式)。 。分子建模技术被应用于探索大环的构象和能量行为。
