Bis[4-(9,9-diMethyl-9,10-dihydroacridine)phenyl]solfone

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 lms), bipolar charge-transporting capability, and high photoluminescence quantum yields (PLQYs).

DMAC-DPS is mainly used as blue dopant material in TADF-OLED devices, due to its bipolar charge-transporting capability.

Thermally activated delayed fluorescent (TADF) blue dopant.

The molecular design of DMAC-DPS (Bis[4-(9,9-diMethyl-9,10-dihydroacridine)phenyl]solfone) underpins its exceptional performance in OLEDs. This molecule consist of a diphenylsulfone center with two 9,9-dimethyl-9,10-dihydroacridine acceptor groups. Its structure facilitates efficient energy transfer, crucial for blue emission, with a HOMO level of 5.9 eV and a LUMO level of 2.9 eV. This optimal energy alignment makes DMAC-DPS an ideal choice for creating vibrant blue hues in OLED displays, enhancing device efficiency and color purity.
