Abstract

<abstract abstract-type="graphical" xml:lang="en" id="adma201405093-abs-0001"> <title> <x xml:space="preserve">Abstract</x> </title> <p> <bold>A stable organic diradicaloid</bold> with an intermolecular quintet at room temperature as a polycrystalline solid is studied. The conclusion is supported by the observation of the Δ<italic>M</italic>_s = ±2 forbidden transition, electron spin resonance (ESR) simulations, and density functional theory (DFT) calculations. In addition, the molecule, as the active component of a device, is an outstanding near‐infrared photodetector with detectivity over 10¹¹ cm Hz^1/2 W^–1 at 1200 nm. <boxed-text content-type="graphic" position="anchor" orientation="portrait"><graphic position="anchor" mimetype="image" xlink:href="ark:/27927/pgj70bf0ks" orientation="portrait" xlink:type="simple" xmlns:xlink="http://www.w3.org/1999/xlink" /></boxed-text></p> </abstract>
