However, routine analytic techniques such as thermogravimetric analysis cannot distinguish the contribution from species adsorbed within pores, species adsorbed on the surface, and gas phase or liquid phase encapsulated in the inter\u2010crystalline space. Herein, we developed a new quantification method based on the cross\u2010polarization (CP) solid\u2010state nuclear magnetic resonance (ssNMR) technique, in which only the species within MOF pores are selectively probed due to the dramatically reduced mobility. Using the commercialized MOF <jats:italic>\u03b1<\/jats:italic>\u2010Mg<jats:sub>3<\/jats:sub>(HCOO)<jats:sub>6<\/jats:sub> as an example, a good linear correlation between Area<jats:sub>guest<\/jats:sub>\/Area<jats:sub>framework<\/jats:sub> (i.\u2009e., the integrated area of guest and framework <jats:sup>13<\/jats:sup>C NMR signals) and guest loading can be observed for several representative molecules such as benzene, tetrahydrofuran (THF), and 1,4\u2010dioxane, clearly revealing the feasibility of CP quantification approach. The effects of guest molecule and corresponding residual mobility on the CP quantification are further discussed by varying the geometry and size of guest molecules. This methodology thus provides an effective and irreplaceable route to evaluate the adsorption performance of porous materials in\u2010depth, especially for liquid\u2010phase adsorption and gas\u2010phase adsorption in which the capillary condensation is not negligible.<\/jats:p>","DOI":"10.1002\/cphc.202400215","type":"journal-article","created":{"date-parts":[[2024,4,19]],"date-time":"2024-04-19T00:19:32Z","timestamp":1713485972000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":3,"title":["Cross\u2010Polarization Solid\u2010State NMR Quantification of Species within Pores of Metal\u2010Organic Frameworks: A Case Study of <i>\u03b1<\/i>\u2010Mg<sub>3<\/sub>(HCOO)<sub>6<\/sub>"],"prefix":"10.1002","volume":"25","author":[{"given":"Changzong","family":"Wu","sequence":"first","affiliation":[{"name":"Tianjin Key Lab for Rare Earth Materials and Applications School of Materials Science and Engineering Nankai University  Tianjin 300350 P.
