Abstract:
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 4,40-bipyridin-1-ium (BP) moieties in the two ends, which also exhibited photo-responsiveness owing to the photoinduced transcis isomerization of azobenzene group.
