Organic Light‐Emitting Diodes A deuterated host (PYD2Cz‐ d 16 ) is introduced in the blue and green thermally activated delayed fluorescence organic light‐emitting diodes (TADF‐OLEDs). By using this deuterated host, the lifetime of the TADF‐OLEDs is extended as presented by Chin‐Yiu Chan, Chihaya Adachi, and co‐workers in the article number 2000057 . Such improvements could be attributed to the non‐crystalline and densely packed behaviors of the film state in deuterated host, resulting in much more balanced carrier‐transporting properties in devices.
