In this work, the diblock copolymer poly(acrylamide\u2010<jats:italic>co<\/jats:italic>\u20101\u2010benzyl\u20103\u2010vinylimidazolium bromide)\u2010block\u2010polyAzobenzene is synthesized through reversible addition\u2212fragmentation chain transfer polymerization. The dynamic host\u2013guest interactions between the host molecule cucurbit[8] uril and guest units are used to fabricate a 3D network of supramolecular hydrogels. Investigations on the properties of the supramolecular hydrogels show that the tensile stress of the sample is 1.46\u00a0MPa, eight times higher than that of hydrogel without liquid\u2010crystalline block copolymer, and the self\u2010healing efficiency of the supramolecular hydrogels at room temperature is 88.3% (fracture stress) and 100% (fracture strain) after 24\u00a0h. Results show that microphase\u2010separated structure plays a key role in the high\u2010strength hydrogel, whereas the host\u2013guest interaction endows the hydrogel with self\u2010healing properties. The supramolecular hydrogels with high mechanical strength, photo\u2010responsivity, injectability, and biocompatibility can be used in various potential applications.<\/jats:p>","DOI":"10.1002\/marc.202200829","type":"journal-article","created":{"date-parts":[[2022,12,9]],"date-time":"2022-12-09T08:05:07Z","timestamp":1670573107000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":17,"title":["High
