A new method for controllable supramolecular polymerization based on ABBA type monomer and cucurbit[8]uril monomer through host-guest interaction and photochemistry is reported. The molecular weight and polydispersity of supramolecular polymers can be well controlled by tuning the molar ratio of these host and guest monomers or by tuning the isomer ratio of azobenzene groups in the guest monomers upon the competitive irradiation of lights. This research provides a general methodology for the control of supramolecular polymerization and the structure of supramolecular polymers.
报道了一种基于ABBA型单体和葫芦[8]脲单体通过主客体相互作用和光化学实现可控超分子聚合的新方法。通过调节这些主客体单体的摩尔比，或在光的竞争性照射下调节客体单体中偶氮苯基团的异构体比例，可以很好地控制超分子聚合物的分子量和多分散性。该研究为超分子聚合的控制和超分子聚合物的结构提供了一种通用方法。
