A series of N–B–O‐embedded novel multiresonant , thermally activated delayed fluorescent (MR‐TADF) emitters have been synthesized. The cover image shows how the molecular orbital characters are regulated through the meta / para B–π–B and O–π–O molecular structure, which achieved ultra‐pure deep‐blue/green emission with high horizontal molecular orientations to boost external quantum efficiency in organic light‐emitting devices (OLEDs).
