Abstract:
A cyanostilbene-based amphiphile (CS) was synthesized, which could self-assemble into non-emissive bilayer vesicles and ultra-thin ribbons. Cucurbit[7]uril (CB[7]) could form an inclusion complex with CS with a significant hypochrome effect, giving a strong blue emission from non-emissive species. CS underwent photoisomerization induced by light irradiation, which allowed the membrane contraction into smaller vesicles.
