A marvelous machine : A 2.5 nm sized molecular machine that behaves like a double ball bearing with three rotors was constructed from two kinds of disk‐shaped ligands, Ag I ions, and dinuclear Pt II bridging complexes (see structure: C red, N blue, O purple, S green, Ag yellow, Pt brown). Motion of the three rotors was found to depend greatly on the degree of interlocking between the two ligands in rotor 2 through helix inversion.
