Abstract

<abstract abstract-type="graphical" xml:lang="en"> <title> <x xml:space="preserve">Abstract</x> </title> <p> <bold>Stepwise construction of functional triazatruxene platforms</bold> allow linking to preorganized diketopyrrolopyrrole bearing thienyl subunits. These dyes exhibit strong absorption until 750 nm in thin films and show favorable redox activity allowing producing efficient organic solar cells when blended in solution with PC₇₁BM. A maximum power conversion efficiency of 5.3% was obtained. <boxed-text content-type="graphic" position="anchor" orientation="portrait"><graphic position="anchor" mimetype="image" xlink:href="ark:/27927/pgg36h2jjnw" orientation="portrait" xlink:type="simple" xmlns:xlink="http://www.w3.org/1999/xlink" /></boxed-text></p> </abstract>
