Abstract

<abstract abstract-type="graphical" xml:lang="en"> <title> <x xml:space="preserve">Abstract</x> </title> <p>Hypofluorous acid is a potent and selective oxidizing agent that can react with thiophene‐containing polymers to change their optoelectronic properties. As L. M. Campos and co‐workers report in their Communication on <ext-link ext-link-type="doi" xlink:type="simple" xmlns:xlink="http://www.w3.org/1999/xlink">page 1832 ff., </ext-link> the thiophene units are converted into nonaromatic thiophene‐1, 1‐dioxides, thereby resulting in materials with increased electron affinity and a smaller optical bandgap. The image depicts the fast chemical transformation of the conjugated polymers.<boxed-text content-type="graphic" position="anchor" orientation="portrait"><graphic position="anchor" mimetype="image" xlink:href="ark:/27927/pgg4sm9qgqj" orientation="portrait" xlink:type="simple" xmlns:xlink="http://www.w3.org/1999/xlink" /></boxed-text></p> </abstract>
