Herein, we report the synthesis and the iodine adsorption properties of croconic acid (<jats:bold>CTPB<\/jats:bold>) and squaric acid (<jats:bold>STPB<\/jats:bold>) containing \u03c0\u2010conjugated novel zwitterionic conjugated porous polymers (CPPs). The CPPs have been synthesized through a condensation reaction of <jats:italic>tris<\/jats:italic>(4\u2010aminophenyl)benzene with croconic acid or squaric acid in high yields (~95\u2009%). The ionic nature of the polymers promoted high iodine\/polyiodide vapour adsorption capacity of up to 4.6\u2005g\/g for <jats:bold>CTPB<\/jats:bold> and 3.5\u2005g\/g for <jats:bold>STPB<\/jats:bold> under ambient pressure at 80\u2009\u00b0C. The zwitterionic framework (croconic acid or squaric acid units) coupled with the aromatic units is expected to effectively capture molecular iodine (I<jats:sub>2<\/jats:sub>) and polyiodides (I<jats:sub>3<\/jats:sub><jats:sup>\u2212<\/jats:sup> and I<jats:sub>5<\/jats:sub><jats:sup>\u2212<\/jats:sup>). The iodine adsorption properties of the polymers have been studied using Fourier\u2010Transform Infrared Spectroscopy (FT\u2010IR), Scanning Electron Microscopy (SEM), Brauner\u2010Emmett\u2010Teller (BET) analysis, and Raman Spectroscopy. Besides this work, there are only three ionic units for effective iodine adsorption. This work demonstrates the importance of zwitterionic units in the porous network reported for iodine adsorption and separation.<\/jats:p>","DOI":"10.1002\/asia.202400808","type":"journal-article","created":{"date-parts":[[2024,9,3]],"date-time":"2024-09-03T03:54:20Z","timestamp":1725335660000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":13,"title":["Croconic Acid Integrated Zwitterionic Conjugated Porous Polymer for Effective Iodine Adsorption"],"prefix":"10.1002","volume":"19","author":[{"ORCID":"https:\/\/orcid.org\/0009-0002-0384-6573","authenticated-orcid":false,"given":"Maruti Vibhuti","family":"Ravikumar","sequence":"first","affiliation":[{"name":"Department of Chemistry National Institute of Technology Karnataka  Surathkal, Karnataka 575025 India"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Atul B.","family":"Nipate","sequence":"additional","affiliation":[{"name":"Department of Chemistry Indian Institute of Technology Dharwad  Dharwad, Karnataka 580007"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0009-0004-7269-4176","authenticated-orcid":false,"given":"M.
