PPF, dibenzo[b,d]furan-2,8-diylbis(diphenylphosphine Oxide), contains an electron donating dibenzo[b,d]furan core and two electron deficient diphenylphosphine oxide units. Due to its electron deficient nature, PPF and PPT can be used as electron transport layer materials, and in some cases, to form exciplex as emitting layer materials in TADF-OLED devices.
