Abstract

<abstract abstract-type="graphical" xml:lang="en" id="aenm201301455-abs-0001"> <title> <x xml:space="preserve">Abstract</x> </title> <p> <bold>A series of conjugated polymers containing benzodithiophene as donor and isoindigo as acceptor</bold> with no, one, two and three thiophene spacer groups is synthesized and characterized. The polymer with bithiophene as a spacer has a superior efficiency of 7.31% in solar cells. This demonstrates an important design strategy to produce polymers for high‐performance solar cells by inserting thiophene spacer groups. <boxed-text content-type="graphic" position="anchor" orientation="portrait"><graphic position="anchor" mimetype="image" xlink:href="ark:/27927/pgg5f3dd1hv" orientation="portrait" xlink:type="simple" xmlns:xlink="http://www.w3.org/1999/xlink" /></boxed-text></p> </abstract>
