通过Hg-II铰链和弯曲的双吡啶配体的结合，选择性地形成M2 L4配位胶囊或M2 L2配位管。这两种结构在室温下可逆地相互转化，以响应金属与配体的比例的调制，并表现出不同的主体-客体相互作用行为。胶囊单独封装大的球形分子，富勒烯C-60和C-70，和结合的客人被释放后，通过简单的添加金属离子的胶囊到管的转变。
An M2L4 coordination capsule or an M2L2 coordination tube was selectively formed by the combination of Hg-II hinges and bent bispyridine ligands. The two structures reversibly interconvert at room temperature in response to modulation of the metal-to-ligand ratio and exhibit different host-guest interaction behavior. The capsule alone encapsulates large spherical molecules, fullerenes C-60 and C-70, and the bound guests are released upon capsule-to-tube transformation by the simple addition of metal ions.
