Abstract

<abstract abstract-type="graphical" xml:lang="en" id="adma201401393-abs-0001"> <title> <x xml:space="preserve">Abstract</x> </title> <p> <bold>Thermally activated delayed fluorescence emitters</bold> with small energy gap between the triplet and singlet (ΔE_ST), TXO‐PhCz and TXO‐TPA, have been successfully synthesized by combining a hole‐transporting TPA/PhCz moiety and an electron‐transporting TXO moiety. Both compounds display efficient solid‐state luminescence with an efficient up‐conversion of the triplet to singlet. OLEDs based on them exhibt high performance up to 21.5%, which is among the best reported for OLEDs. <boxed-text content-type="graphic" position="anchor" orientation="portrait"><graphic position="anchor" mimetype="image" xlink:href="ark:/27927/pgh112xhp6v" orientation="portrait" xlink:type="simple" xmlns:xlink="http://www.w3.org/1999/xlink" /></boxed-text></p> </abstract>
