reactions. Self-assembly of the catenanes requires the formation of ordered intertwined chains and is driven by bifurcated hydrogen bonds, with pi stacking only playing a lesser role. The understanding gained from the computational study was used to predict the possibility of a new rotaxane-forming system that does not permit catenane formation. The predictions were confirmed by the successful synthesis and
四种不同试剂系统的分子模型表明,气相和溶液中超分子相互作用的(自由)能可以解释在经典酰胺-中形成的不同反应产物(即各种大小的大环,链烯和线性低聚物)。形成链烷的反应。链烯的自组装需要形成有序的缠结链,并由分叉的氢键驱动,而pi堆积仅起较小的作用。从计算研究中获得的理解被用于预测不允许形成链烷的新型轮烷形成系统的可能性。两种新型轮烷的成功合成和表征(包括X射线晶体学)证实了这些预测。
