Abstract

<abstract abstract-type="graphical" xml:lang="en"> <title> <x xml:space="preserve">Abstract</x> </title> <p> <bold>Trapped in a porous material</bold>: The position of adsorbed CO₂ in a nanoporous coordination framework was determined using a combination of techniques including single‐crystal X‐ray diffraction, in situ X‐ray powder diffraction coupled with differential scanning calorimetry, and theoretical calculations. The study reveals that the adsorbed CO₂ stays in a "pocket" between two phenyl rings, interacting with the aromatic electron density (see picture).<boxed-text content-type="graphic" position="anchor" orientation="portrait"><graphic position="anchor" mimetype="image" xlink:href="ark:/27927/pgg1v48ggzh" orientation="portrait" xlink:type="simple" xmlns:xlink="http://www.w3.org/1999/xlink" /></boxed-text></p> </abstract>
