generated. The presence of large aromatic naphthalene diimide moieties on the scaffold of the molecular tweezers strongly influences their coordination-driven self-assembly. It was found that these additional stacking interactions lead to the cooperative formation of a homocomplex, to the self-sorted assembly of a hetero complex, and to the binding of non-coordinating aromatic guests.
将可控动态特征引入合成受体代表了迈向“智能”自适应纳米设备的一步。我们在此报告了我们对动态分子镊子构建的研究,其中底物的结合通过
金属离子配位诱导的受体形状转换进行变构控制。使用一维、二维核磁共振光谱和 X 射线晶体学来鉴定生成的
金属超分子实体的性质。分子镊子支架上大

亚胺部分的存在强烈影响其配位驱动的自组装。发现这些额外的堆积相互作用导致同质复合物的协同形成、异质复合物的自分类组装以及非配位芳香客体的结合。
