blue‐emitting iridium dendrimer, namely B‐G2, has been successfully designed and synthesized with a second‐generation oligocarbazole as the dendron, which is covalently attached to the emissive tris[2‐(2,4‐difluorophenyl)‐pyridyl]iridium(III) core through a nonconjugated link to form an efficient self‐host system in one dendrimer. Unlike small molecular phosphors and other phosphorescentdendrimers, B‐G2 shows
