Organic Light‐Emitting Diodes In many thermally activated delayed fluorescence (TADF) organic light‐emitting diodes (OLEDs), efficiency and lifespan have shown a trade‐off relationship. In article number 2102141, Soo‐Ghang Ihn and coworkers present phosphine oxide‐free hosts designed via a dipole moment‐ and molecular orbital‐engineering, which enhance the device efficiency and stability simultaneously. This approach paves the way for the commercialization of TADF OLED technology.
