DMAC-DPS is great for applications in TADF-OLED devices, thanks to its rather broad blue emission nature with a full width at half-maximum of ≈ 80 nm, short lived excited-state (≈3.0 µs in solid ﬁlms), bipolar charge-transporting capability, and high photoluminescence quantum yields (PLQYs).
DMAC-DPS can be used either as a deep blue emitter, or as a blue dopant material in TADF-OLED devices.
