Abstract

<abstract abstract-type="graphical" xml:lang="en" id="adma201403914-abs-0001"> <title> <x xml:space="preserve">Abstract</x> </title> <p> <bold>Copper thiocyanate (CuSCN) is introduced</bold> as a hole‐injection/hole‐transport layer (HIL/HTL) for solution‐processed organic light‐emitting diodes (OLEDs). The OLED devices reported here with CuSCN as HIL/HTL perform significantly better than equivalent devices fabricated with a PEDOT:PSS HIL/HTL, and solution‐processed, phosphorescent, small‐molecule, green OLEDs with maximum luminance ≥10 000 cd m^‐2, maximum luminous efficiency ≤50 cd A^‐1, and maximum luminous power efficiency ≤55 lm W^‐1 are demonstrated. <boxed-text content-type="graphic" position="anchor" orientation="portrait"><graphic position="anchor" mimetype="image" xlink:href="ark:/27927/pgh30v92jvr" orientation="portrait" xlink:type="simple" xmlns:xlink="http://www.w3.org/1999/xlink" /></boxed-text></p> </abstract>
