However, conventional hydrodesulfurization encounters difficulties due to severe operating conditions and limited efficacy against aromatic heterocyclic sulfur compounds. Adsorptive desulfurization offers notable advantages under milder conditions. In this investigation, topology-guided pore engineering was utilized to fabricate porous aromatic frameworks (PAFs) with distinct pore structures through Suzuki\u2013Miyaura cross-coupling. Notably, PBPAF-2, despite its lower specific surface, demonstrates significantly improved mass transfer kinetics attributed to its unique mesoporous channel (2.13 nm), resulting in notably prolonged dynamic breakthrough retention times compared to other materials in the series. Analysis using synchrotron-assisted FT-IR spectroscopy reveals a blue-shift in benzene ring characteristic peaks following adsorption of dibenzothiophene and benzothiophene, indicating that \u03c0-\u03c0 interactions between electron-rich aromatic rings in PAFs and thiophenic rings are the primary driving force for adsorption. This work proposes a dual-factor synergistic design strategy of \u201cmass transfer optimization\u2013electron cloud matching\u201d, offering a new strategy for the development of highly efficient adsorbents.<\/jats:p>","DOI":"10.3390\/nano15231815","type":"journal-article","created":{"date-parts":[[2025,12,2]],"date-time":"2025-12-02T08:49:22Z","timestamp":1764665362000},"page":"1815","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":4,"title":["Design of Porous Aromatic Frameworks for Adsorptive Desulfurization: Synergistic Modulation via \u03c0-\u03c0 Interactions and Mesopores"],"prefix":"10.3390","volume":"15","author":[{"given":"Tiantian","family":"Li","sequence":"first","affiliation":[{"name":"School of Chemical Engineering and Technology, Xuzhou College of Industrial Technology, Xuzhou 221140, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Xiaowen","family":"Li","sequence":"additional","affiliation":[{"name":"School of Chemical Engineering and Technology, Xuzhou College of Industrial Technology, Xuzhou 221140, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Hao","family":"Wu","sequence":"additional","affiliation":[{"name":"School of Chemical Engineering and Technology, Xuzhou College of Industrial Technology, Xuzhou 221140, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Guangxia","family":"Shi","sequence":"additional","affiliation":[{"name":"School of Chemical Engineering and Technology, Xuzhou College of Industrial Technology, Xuzhou 221140, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yizhi","family":"Zeng","sequence":"additional","affiliation":[{"name":"Xi\u2019an Research Institute of High Technology, Xi\u2019an 710025, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Dong","family":"Xu","sequence":"additional","affiliation":[{"name":"Nanjing Institute of Environmental Sciences, Ministry of Ecology and Environment, Nanjing 210042, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-8380-7859","authenticated-orcid":false,"given":"Dingming","family":"Xue","sequence":"additional","affiliation":[{"name":"Nanjing Institute of Environmental Sciences, Ministry of Ecology and Environment, Nanjing 210042, China"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2025,11,30]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"2100442","DOI":"10.1002\/adfm.202100442","article-title":"Molybdenum dioxide nanoparticles anchored on nitrogen-doped carbon nanotubes as oxidative desulfurization catalysts: Role of electron transfer in activity and reusability","volume":"31","author":"Zou","year":"2021","journal-title":"Adv.
