A photodegradable supramolecular polymer was constructed using cucurbit[8]uril (CB[8]) and an alkoxyanthracene guest. The monomeric unit was photostable because of the intramolecular donor-acceptor interaction. However, upon complexation with CB[8], the photolysis of alkoxyanthracene was enhanced, which endowed the supramolecular polymer with great photoreactivity.
使用葫芦[8]脲(CB[8])和烷氧基蒽客体构建了一种可光降解的超分子聚合物。由于分子内供体-受体相互作用,单体单元具有光稳定性。然而,与CB[8]络合后,烷氧基蒽的光解增强,这赋予了超分子聚合物很大的光反应活性。
