However, they suffer from a limited energy density compared to lithium\u2010ion batteries. This limitation can be overcome by developing novel electrode materials, with covalent organic frameworks (COFs) standing out as a particularly intriguing option. Herein, peri\u2010xanthenoxanthene (PXX) has been integrated for the first time into a COF scaffold to take advantage of its straightforward synthesis, chemical stability, \u03c0\u2010conjugated backbone, and heteroatom content endowing reversible redox reactions at low potentials. Two novel hexagonal COFs have been designed and synthesized by tethering of a PXX\u2010diamine unit having a C<jats:sub>2<\/jats:sub> symmetry with two distinct tris\u2010aldehydes acting as C<jats:sub>3<\/jats:sub>\u2010symmetric cornerstones, i.e., triformyl benzene (TFB) and triformylphloroglucinol (Tp), ultimately yielding COF PXX(PhNH<jats:sub>2<\/jats:sub>)<jats:sub>2<\/jats:sub>\u2010TFB and COF PXX(PhNH<jats:sub>2<\/jats:sub>)<jats:sub>2<\/jats:sub>\u2010Tp, respectively. As cathodes in Zn\u2010HSCs, COF PXX(PhNH<jats:sub>2<\/jats:sub>)<jats:sub>2<\/jats:sub>\u2010Tp exhibits a remarkable specific capacitance, energy, and power densities (237\u2009F\u2009g<jats:sup>\u22121<\/jats:sup>, 106.6\u2009Wh\u2009kg<jats:sup>\u22121<\/jats:sup>, and 3.0\u2009kW\u2009kg<jats:sup>\u22121<\/jats:sup>, respectively), surpassing those of COF PXX(PhNH<jats:sub>2<\/jats:sub>)<jats:sub>2<\/jats:sub>\u2010TFB (109\u2009F\u2009g<jats:sup>\u22121<\/jats:sup>, 49.1\u2009Wh\u2009kg<jats:sup>\u22121<\/jats:sup>, and 0.67\u2009kW\u2009kg<jats:sup>\u22121<\/jats:sup>). Importantly, both COFs display outstanding long\u2010term stability, over 5000 charge\/discharge cycles, with capacitance retention &gt;92%. These findings underscore the potential of PXX\u2010based COFs as high\u2010performance cathode materials for HSCs, thereby offering a promising new avenue for energy storage technologies.<\/jats:p>","DOI":"10.1002\/smsc.202400031","type":"journal-article","created":{"date-parts":[[2024,4,27]],"date-time":"2024-04-27T04:19:30Z","timestamp":1714191570000},"source":"Crossref","is-referenced-by-count":13,"title":["Peri\u2010Xanthenoxanthene\u2010Based Covalent Organic Frameworks for High\u2010Performance Aqueous Zn\u2010Ion Hybrid Supercapacitors"],"prefix":"10.1002","volume":"4","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-5209-9338","authenticated-orcid":false,"given":"Cataldo","family":"Valentini","sequence":"first","affiliation":[{"name":"Nanochemistry LaboratoryInstitut de Science et d\u2019Ing\u00e9nierie Supramol\u00e9culaires (I.S.I.S.)
