bearing a carboxyl group. The supramolecular interactions between these guests and macrocyclic hosts cucurbit[7]uril (CB7) and cucurbit[8]uril (CB8) has been studied. We have demonstrated that the binding modes of the complexes depend on the type of central bridge present in the guest molecules and the size of the macrocycle. We have also showed that the binding mode between cucurbiturils and guests
我们制备了有机客体分子,其中两个吡啶环通过带有羧基的芳族/脂肪族桥连接。研究了这些客体与大环宿主葫芦[7] uril(CB7)和葫芦[8] uril(CB8)之间的超分子相互作用。我们已经证明,复合物的结合方式取决于客体分子中存在的中央桥的类型和大环的大小。我们还显示了葫芦科和带有芳香桥的客体之间的结合方式与pH无关。另一方面,包含脂族桥和CB7的客体形成了假轮烷,其表现为pH驱动的分子开关。
