These supramolecular gels are frequently metastable, implying that their properties are kinetically controlled to some extent. Here, we report on the in situ supramolecular gel formation by mixing 1,3-cyclohexane diamine (1) and isocyanate derivative (2) without any catalysis at room temperature in various organic solvents. A mixture of building blocks 1 and 2 in various organic solvents, dichloromethane, tetrahydrofuran, chloroform, toluene, and 1,4-dioxane, resulted in the stable formation of supramolecular gel at room temperature within 60\u2013100 s. This gel formation was caused by the generation of urea moieties, which allows for the formation of intermolecular hydrogen-bonding interactions via reactions 1 and 2. In situ supramolecular gels demonstrated a typical entangled fiber structure with a width of 600 nm and a length of several hundred \u03bcm. In addition, the supramolecular gels were thermally reversible by heating and cooling. The viscoelastic properties of supramolecular gels in strain and frequency sweets were enhanced by increasing the concentration of a mixed 1 and 2. Furthermore, the supramolecular gels displayed a thixotropic effect, indicating a thermally reversible gel.<\/jats:p>","DOI":"10.3390\/polym14030400","type":"journal-article","created":{"date-parts":[[2022,1,20]],"date-time":"2022-01-20T22:51:06Z","timestamp":1642719066000},"page":"400","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":6,"title":["In Situ Supramolecular Gel Formed by Cyclohexane Diamine with Aldehyde Derivative"],"prefix":"10.3390","volume":"14","author":[{"given":"Jae-Hyeon","family":"Park","sequence":"first","affiliation":[{"name":"Department of Chemistry, Research Institute of Natural Sciences, Gyeongsang National University, Jinju 52828, Korea"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Min-Hye","family":"Kim","sequence":"additional","affiliation":[{"name":"Department of Chemistry, Research Institute of Natural Sciences, Gyeongsang National University, Jinju 52828, Korea"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Moo-Lyong","family":"Seo","sequence":"additional","affiliation":[{"name":"Department of Chemistry, Research Institute of Natural Sciences, Gyeongsang National University, Jinju 52828, Korea"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-4456-0128","authenticated-orcid":false,"given":"Ji-Ha","family":"Lee","sequence":"additional","affiliation":[{"name":"Chemical Engineering Program, Graduate School of Advanced Science and Engineering, Hiroshima University, 1-4-1 Kagamiyama, Higashi-Hiroshima 739-8527, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-8936-2272","authenticated-orcid":false,"given":"Jong-Hwa","family":"Jung","sequence":"additional","affiliation":[{"name":"Department of Chemistry, Research Institute of Natural Sciences, Gyeongsang National University, Jinju 52828, Korea"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2022,1,20]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"4226","DOI":"10.1039\/C6CS00124F","article-title":"Applying low-molecular weight supramolecular gelators in an environmental setting\u2014Self-assembled gels as smart materials for pollutant removal","volume":"45","author":"Okesola","year":"2016","journal-title":"Chem.
