Abstract

<abstract abstract-type="graphical" xml:lang="en" id="adma201500577-abs-0001"> <title> <x xml:space="preserve">Abstract</x> </title> <p> <bold>Arylene linkers</bold> in a series of new tetraaza­benzodifluoranthene diimide dimers enable tuning of the 3D molecular structure of nonfullerene electron acceptors, facilitating observation of dramatic variation of the power conversion efficiency from 2.6% to 6.4% as the twist angle between the monomeric building blocks in the dimer is varied. <graphic position="anchor" mimetype="image" xlink:href="ark:/27927/pgjqk1cp1t" orientation="portrait" xlink:type="simple" xmlns:xlink="http://www.w3.org/1999/xlink" /></p> </abstract>
