In article number 1808022 , Satoru Ohisa, Yong‐Jin Pu, Junji Kido, and co‐workers develop a solution‐processed phosphorescent tandem organic light‐emitting device exhibiting extremely small efficiency roll‐off. A newly developed thermally activated fluorescent host molecule, whose shape is like a phoenix, allows for efficient energy transfer to orange phosphorescent dopants, resulting in the great suppression of efficiency roll‐off.
