For decades, chemists believed that assembling rotaxanes required carefully designed molecular recognition between a ring and an axle, or rod-shaped, unit. Researchers have now flipped this paradigm, showing that a flexible molecular chain can direct the formation of the ring around itself #chemsky🧪

A simpler way to make rotaxanes
No need for metals or recognition sites to build these molecular machines
