| dc.description.abstract | Efficient reverse intersystem crossing (RISC) is an important process for thermally activated delayed fluorescence (TADF) to suppress efficiency roll-off in organic LEDs (OLEDs). Enhancing spin–orbit coupling is effective for fast RISC and is achieved by mediating a locally excited triplet state when RISC occurs between charge transfer states. Here, we experimentally confirmed that efficient RISC occurred in triarylborane-based TADF emitters named Phox-[Me]π, Phox-[MeO]π, and [MeO]3Ph-[FMe]π. The three emitters showed large RISC rate constants exceeding 10⁶ s⁻¹. The Phox-[Me]π-based OLED exhibited higher maximum external quantum efficiency (EQEₘₐₓ = 10.0%) compared to the Phox-[MeO]π-based OLED (EQEₘₐₓ = 6.7%). | en |
