Using the Schiff base formation reaction, a linear centrally cucurbit[7]uril(CB[7])‐encircled [2]peseudorotaxane with aldehyde groups on both ends was condensed with a 90°carbazole 3,6‐diamine to generate a square [5]catenane, featured by four equal [2]rotaxanes at each side, demonstrating an effective way to integrate interlocked molecules in order.
