A cucurbit[8]uril recognized rigid supramolecular polymer with photo-stimulated responsiveness

A rigid supramolecular polymer was constructed in aqueous solution via cucurbit[8]uril (CB[8]) host recognition with a rigid monomer containing an azobenzene unit and two 4,4′-bipyridin-1-ium (BP) moieties in the two ends, which also exhibited photo-responsiveness owing to the photoinduced trans–cis isomerization of azobenzene group.
