Abstract

<abstract abstract-type="graphical" xml:lang="en" id="adma201402535-abs-0001"> <title> <x xml:space="preserve">Abstract</x> </title> <p> <bold>An exciton‐stimulated molecular transformation</bold> in an organic light‐emitting diode (OLED) on a time scale of a few seconds under electrical bias is shown to reach nearly 100% under standard operating conditions, leading to color switching. It is reversible in both a thin film and an OLED when sufficient thermal energy is supplied. Such an exciton‐stimulated molecular transformation suggests a new process which may be exploited for applications such as electrochromic and memory devices. <boxed-text content-type="graphic" position="anchor" orientation="portrait"><graphic position="anchor" mimetype="image" xlink:href="ark:/27927/pgh2cgh07ns" orientation="portrait" xlink:type="simple" xmlns:xlink="http://www.w3.org/1999/xlink" /></boxed-text></p> </abstract>
