Abstract

<abstract abstract-type="graphical" xml:lang="en"> <title> <x xml:space="preserve">Abstract</x> </title> <p>Dumbbell‐shaped molecules can be created by linking functional triazatruxene platforms to highly fluorescent diketopyrrolopyrrole dyes. The association with [6, 6]‐phenyl‐C71‐butyric acid methyl ester [PC71BM] electron acceptor produces a self‐supporting association capable of photon absorption over a large window and of charge separation in bulk heterojunction solar cells, giving rise to efficient photo‐to‐current conversion reaching 5.3%. <ext-link ext-link-type="doi" xlink:type="simple" xmlns:xlink="http://www.w3.org/1999/xlink">On page 1118</ext-link>, Nicolas Leclerc, Raymond Ziessel, and co‐workers describe how these green materials are prepared and studied within the framework of organic solar cells. <boxed-text content-type="graphic" position="anchor" orientation="portrait"><graphic position="anchor" mimetype="image" xlink:href="ark:/27927/pgg36h2jqqk" orientation="portrait" xlink:type="simple" xmlns:xlink="http://www.w3.org/1999/xlink" /></boxed-text></p> </abstract>
