title: A molecular pulley based on a triply interlocked [2]rotaxane.
abstract: A novel triply interlocked [2]rotaxane based on a triptycene-derived tris(crown ether) host and a guest embedded with three dibenzylammonium and three N-methyltriazolium recognition sites was designed and synthesized, which showed pulley-like shuttling motion controlled by acid and base.
