请让我进去！当将双阴离子线添加到由两个带正电的金属络合物组成的分子笼中时，定量地形成一种新型（伪）轮烷。旋转机制遵循两种替代方式，具体取决于金属（Pd 与 Pt）和客体的塞子尺寸（见图）。
Please let me in! A new kind of (pseudo) rotaxane is formed quantitatively when a bis-anionic thread is added to a molecular cage comprised of two positively charged metal complexes. The rotaxanation mechanism follows two alternative ways depending on the metal (Pd vs. Pt) and the stopper size of the guest (see figure).
