Abstract

<abstract abstract-type="graphical" xml:lang="en" id="adma201405897-abs-0001"> <title> <x xml:space="preserve">Abstract</x> </title> <p> <bold>The substitution of rare metals</bold> such as iridium and platinum in light‐emitting materials is a key step to enable low‐cost mass‐production of organic light‐emitting diodes (OLEDs). Here, it is demonstrated that using a solution‐processed, fully bridged dinuclear Cu(I)‐complex can yield very high efficiencies. An optimized device gives a maximum external quantum efficiency of 23 ± 1% (73 ± 2 cd A⁻¹). <boxed-text content-type="graphic" position="anchor" orientation="portrait"><graphic position="anchor" mimetype="image" xlink:href="ark:/27927/pgjhx62n6p" orientation="portrait" xlink:type="simple" xmlns:xlink="http://www.w3.org/1999/xlink" /></boxed-text></p> </abstract>
