A novel class of hosts suitable for solution processing has been developed based on a conjugated dendritic scaffold. By increasing the dendron generation, the highest occupied molecular orbital (HOMO) energy level can be tuned to facilitate hole injection, while the triplet energy remains at a high level, sufficient to host high‐energy‐triplet emitters. A power‐efficient blue‐electrophosphorescent device based on H2 (see figure) is presented.
