Abstract

<abstract abstract-type="graphical" xml:lang="en" id="adma201404806-abs-0001"> <title> <x xml:space="preserve">Abstract</x> </title> <p> <bold>The first example for thienoacene derivatives</bold> with selective growth of different crystal polymorphs is simply achieved by solution‐phase self‐assembly. Compared with platelet‐shaped α‐phase crystals, organic field‐effect transistors (OFETs) based on microribbon‐shaped β‐phase crystals show a hole mobility up to 18.9 cm² V⁻¹ s⁻¹, which is one of the highest values for p‐type organic semiconductors measured under ambient conditions. <boxed-text content-type="graphic" position="anchor" orientation="portrait"><graphic position="anchor" mimetype="image" xlink:href="ark:/27927/pgh3pgk71sx" orientation="portrait" xlink:type="simple" xmlns:xlink="http://www.w3.org/1999/xlink" /></boxed-text></p> </abstract>
