A photodegradable supramolecular polymer was constructed with cucurbit[8]uril (CB[8]) and alkoxyanthracene guest. The monomeric unit was photostable because of the intramolecular donor-acceptor interaction. However, upon complexation with CB[8], photolysis of alkoxyanthracene was enhanced, which endowed the supramolecular polymer with great photoreactivity.

尿素(CB [8])和烷氧基
蒽客体构建了可光降解的超分子聚合物。由于分子内供体-受体的相互作用,单体单元是光稳定的。然而,与CB [8]络合后,烷氧基
蒽的光解作用增强,这赋予了超分子聚合物很大的光反应性。
