An M2L4 Molecular Capsule with an Anthracene Shell: Encapsulation of Large Guests up to 1 nm

A new M2L4 molecular capsule with an aromatic shell was prepared using two Pd(II) ions and four bisanthracene ligands. The self-assembled capsule possesses a cavity with a diameter of ∼1 nm that can encapsulate medium-sized spherical and planar molecules as well as a very large molecule (C60) in quantitative yields. The encapsulated guests are fully segregated and shielded from the external environment by the large anthracene panels.

一种新型的M2L4分子胶囊，其外壳具有芳香性，通过采用两个Pd(II)离子和四种双蒽配体成功制备。该自组装胶囊内含一个直径约为1纳米的空腔，能够以定量产率封装中等大小球形和平面分子，甚至能够封装非常大的分子（如C60）。被封装的客体分子完全被大型蒽面板隔离和屏蔽，免受外部环境的影响。
