In this context, a novel approach is undertaken, employing the rigid triptycene as a foundational building block. This strategy is coupled with the incorporation of dichloromethane and 1,3-dichloropropane, serving as rigid and flexible linkers, respectively. This combination not only enables cost-effective fabrication but also expedites the creation of two distinct triptycene-based hypercrosslinked polymers (HCPs), identified as PTN-70 and PTN-71. Surprisingly, despite PTN-71 manifesting an inferior Brunauer\u2013Emmett\u2013Teller (BET) surface area when compared to the rigidly linked PTN-70, it showcases remarkably enhanced methane adsorption capabilities, particularly under high-pressure conditions. At a temperature of 275 K and a pressure of 95 bars, PTN-71 demonstrates an impressive methane adsorption capacity of 329 cm3 g\u22121. This exceptional performance is attributed to the unique flexible network structure of PTN-71, which exhibits a pronounced swelling response when subjected to elevated pressure conditions, thus elucidating its superior methane adsorption characteristics. The development of these advanced materials not only signifies a significant stride in the realm of methane storage but also underscores the importance of tailoring the structural attributes of hypercrosslinked polymers for optimized gas adsorption performance.<\/jats:p>","DOI":"10.3390\/polym16010156","type":"journal-article","created":{"date-parts":[[2024,1,4]],"date-time":"2024-01-04T04:05:38Z","timestamp":1704341138000},"page":"156","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":4,"title":["Rigidity with Flexibility: Porous Triptycene Networks for Enhancing Methane Storage"],"prefix":"10.3390","volume":"16","author":[{"given":"Fei","family":"Guo","sequence":"first","affiliation":[{"name":"National Engineering Laboratory for Advanced Yarn and Fabric Formation and Clean Production, Technology Institute, Wuhan Textile University, Wuhan 430200, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Hui","family":"Ma","sequence":"additional","affiliation":[{"name":"College of Life Science and Technology, National Engineering Research Center for Nanomedicine, Huazhong University of Science and Technology, Wuhan 430074, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Bin-Bin","family":"Yang","sequence":"additional","affiliation":[{"name":"College of Life Science and Technology, National Engineering Research Center for Nanomedicine, Huazhong University of Science and Technology, Wuhan 430074, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Zhen","family":"Wang","sequence":"additional","affiliation":[{"name":"National Engineering Laboratory for Advanced Yarn and Fabric Formation and Clean Production, Technology Institute, Wuhan Textile University, Wuhan 430200, China"},{"name":"College of Life Science and Technology, National Engineering Research Center for Nanomedicine, Huazhong University of Science and Technology, Wuhan 430074, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Xiang-Gao","family":"Meng","sequence":"additional","affiliation":[{"name":"School of Chemistry, Central China Normal University, Wuhan 430079, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jian-Hua","family":"Bu","sequence":"additional","affiliation":[{"name":"Xi\u2019an Modern Chemistry Research Institute, Xi\u2019an 710065, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-5190-7396","authenticated-orcid":false,"given":"Chun","family":"Zhang","sequence":"additional","affiliation":[{"name":"College of Life Science and Technology, National Engineering Research Center for Nanomedicine, Huazhong University of Science and Technology, Wuhan 430074, China"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2024,1,4]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"43","DOI":"10.1023\/A:1009673830619","article-title":"Porous Adsorbents for Vehicular Natural Gas Storage: A Review","volume":"5","author":"Menon","year":"1998","journal-title":"J.
