Water soluble supramolecular polymers are especially important due to their superior biocompatibility and environmental adaptation, which determined they have wide applications in various areas, such as drug delivery, self-healing, shape memory. On the other hand, macrocyclic compounds are the most used building blocks in the preparation of supramolecular polymers. Macrocycle-based supramolecular polymers, which introduce the host-guest interaction in the system, endow these polymers with interesting and smart physicalchemical properties. In this review, we summarized recent studies about supramolecular polymers in aqueous solution based on macrocyclic compounds.

In this work, we found that ethylenediamine can enrich the electron state of Ni and make the azobenzene easily desorb from the surface of the catalyst, which effectively inhibits the further hydrogenation to aniline and greatly improves the selectivity of azobenzene. When the ratio of Ni and ethylenediamine is 1:10, the yield of the azobenzene can reach 95.5%.
