A multicomponent pseudorotaxane quadrilateral was reversibly toggled between three distinct switching states. Switching in the forward conversion was achieved by addition of H and K ions, and switching in the reverse direction was performed by addition of 18-crown-6 and 1-aza-18-crown-6. In both the forward and backward ways, the inputs operated an AND gate with distinct catalytic outputs. While in the forward direction the logic AND operation starting from a heteroleptic five-component assembly turned "ON" an imine hydrolysis as output (AND-1), in the inverse direction a Michael addition was ignited as the output starting from a seven-component aggregate following the AND gate logic (AND-2).
一种多组分伪轮烷四边形可在三种不同的开关状态之间可逆地切换。正向转换的切换是通过添加 H 和 K 离子实现的，而反向切换是通过添加 18-冠-6 和 1-氮杂-18-冠-6 实现的。在正向和反向两种情况下，输入通过具有明显催化输出的与门进行操作。在正向方向上，从杂多组分五组件组装开始的逻辑与操作将“ON”作为输出（AND-1），将imine 水解作为输出，而在反向方向上，从遵循与门逻辑的七组分聚合体开始，引发迈克尔加成作为输出（AND-2）。
