Abstract

<abstract abstract-type="graphical" xml:lang="en"> <title> <x xml:space="preserve">Abstract</x> </title> <p> <bold>Ambipolar organic semiconductors</bold> that can conduct both hole and electron carriers have received increasing attention in recent years. In their Full Paper on <ext-link ext-link-type="doi" xlink:type="simple" xmlns:xlink="http://www.w3.org/1999/xlink">page 1068 ff.</ext-link>, Deqing Zhang and co‐workers report two conjugated molecules containing <italic>E</italic>‐(1, 2‐difluorovinyl) and diketopyrrolopyrrole (DPP) moieties. One of them, DPP‐2F, displays an ambipolar semiconducting behavior with hole and electron mobilities reaching 0.42 and 0.80 cm² V⁻¹ s⁻¹, respectively. The present study clearly demonstrates that (<italic>E</italic>)‐2‐(1, 2‐difluorovinyl) is a useful electron‐withdrawing block to tune frontier orbital energies and extend conjugation.<boxed-text content-type="graphic" position="anchor" orientation="portrait"><graphic position="anchor" mimetype="image" xlink:href="ark:/27927/pgg4tpkzg1p" orientation="portrait" xlink:type="simple" xmlns:xlink="http://www.w3.org/1999/xlink" /></boxed-text></p> </abstract>
