Description
<jats:title>Robust assembly of aromatic molecules</jats:title> <jats:p> Organic materials can exhibit high porosity, but the structures often collapse or decompose at high temperatures. Yamagishi <jats:italic>et al.</jats:italic> synthesized an aromatic molecule that bears a symmetrical outer shell of three dipyridylphenyl wedges and crystallized it from highly dielectric solvents. Porous crystals formed with complex pore-wall structures that resulted from labile C–H⋯N bonds and van der Waals forces. Despite the weakness of these interactions, the porous structure was stable up to 202°C and could be recovered after collapse by exposure to solvent vapor. </jats:p> <jats:p> <jats:italic>Science</jats:italic> , this issue p. <jats:related-article xmlns:xlink="http://www.w3.org/1999/xlink" ext-link-type="doi" issue="6408" page="1242" related-article-type="in-this-issue" vol="361" xlink:href="10.1126/science.aat6394">1242</jats:related-article> </jats:p>
