Through the use of some time-tested chemistry and clever monomer design, chemists led by the University of Chicago’s Stuart J. Rowan have managed to make a record-breaking polycatenane that mechanically links 26 ring-shaped molecules in a single chain. Their branched polycatenanes are even larger, boasting as many as 130 rings in a single mechanically interlocked molecule. The structures could have usual properties and would allow chemists to . . .
