title: A tristable [2]rotaxane that is doubly gated by foldamer and azobenzene kinetic barriers.
abstract: A hydrogen bonded foldamer unit and an azobenzene unit have been incorporated into the linear component of a tristable [2]rotaxane to give rise to a doubly gated switching system tuned by the folding-defolding of the foldamer unit and the photo-initiated trans-cis isomerization of the azobenzene unit.
