Masters of glowing potions ! A pyridinecarbonitrile derivative, specifically isonicotinotitrile, can generate a novel series of thermally activated delayed fluorescent (TADF) emitters by combining suitable donor unit(s) such as 9,10‐dihydro‐9,9‐dimethylacridine or phenoxazine. These emitters possessed reasonably high photoluminescent quantum yields of 70—79% and led to high‐power‐efficiency blue‐to‐green organic light‐emitting diodes (OLEDs) with a very low drive voltage and high external quantum efficiency of over 20 %. More information can be found in the Full Paper by Hisahiro Sasabe, Junji Kido et al. on page 648 in Issue 6, 2017 (DOI: 10.1002/asia.201601641).
