Abstract

<abstract abstract-type="graphical" xml:lang="en" id="adma201302007-abs-0001"> <title> <x xml:space="preserve">Abstract</x> </title> <p> <bold>Two new high‐performance DPP‐containing donor molecules</bold> employing a molecular architecture with three DPP chromorphores (<italic>tri</italic>‐DPP) in conjugated backbones are synthesized and characterized. The two <italic>tri</italic>‐DPP molecules with only a structural difference on alkyl substitutions, when blended with PC₇₁BM, lead to power conversion efficiencies up to 4.8 and 5.5%, respectively. <boxed-text content-type="graphic" position="anchor" orientation="portrait"><graphic position="anchor" mimetype="image" xlink:href="ark:/27927/pgg3t123p3w" orientation="portrait" xlink:type="simple" xmlns:xlink="http://www.w3.org/1999/xlink" /></boxed-text></p> </abstract>
