title: Sodium and barium cation-templated synthesis and cation-induced molecular pirouetting of a pyridine N-oxide containing [2]rotaxane.
abstract: Sodium and barium metal cation templation has been used to construct a novel pyridine N-oxide containing [2]rotaxane. Upon addition and removal of metal cations, the macrocyclic component is observed to undergo a pirouetting motion around the pyridine N-oxide axle.
