CAS Number 1477512-32-5
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).
PLQYs of blue-emitting DMAC–DPS can be increased from 0.80 to 0.90 by changing the host from mCP to bis(2-(diphenylphosphino)phenyl)ether oxide (DPEPO).
DMAC-DPS is normally used as a blue dopant material in TADF-OLED devices.
