説明
<jats:title>Slip-Sliding Apart</jats:title> <jats:p> One versatile means of synthesizing nanometer-scale cylinders has been to start with ring-shaped molecules that stack on top of each other. <jats:bold> Huang <jats:italic>et al.</jats:italic> </jats:bold> (p. <jats:related-article xmlns:xlink="http://www.w3.org/1999/xlink" ext-link-type="doi" page="1521" related-article-type="in-this-issue" vol="337" xlink:href="10.1126/science.1224741">1521</jats:related-article> ; see the Perspective by <jats:bold> <jats:related-article xmlns:xlink="http://www.w3.org/1999/xlink" ext-link-type="doi" issue="6101" page="1462" related-article-type="in-this-issue" vol="337" xlink:href="10.1126/science.1228178">Zhang and Aida</jats:related-article> </jats:bold> ) took this approach a step further by giving the rings a flexible diameter. Specifically, rings were prepared consisting of six v-shaped building blocks with hydrophobic sides that could slide back and forth along one another and thereby expand or contract the pore at the center. The rings spontaneously stacked to form tubes in dilute aqueous solution, and heating induced contraction of the whole tube in a process that was readily reversible on cooling. </jats:p>
