PPF, ETL material and host material for effective triplet excitons confinement
High-purity (>99.0%) and available online for priority dispatch
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 their electron deficient nature, both PPF and PPT can be used as electron transport layer materials, and in some cases, to form exciplex with electron deficient donors, i.e. TAPC as emitting layer materials in TADF-OLED devices.
PPF shows a high triplet energy (ET = 3.1 eV) and it also can be used as host material for effective triplet excitons confinement in the emissive layer. PPF could also be used as exciton blocking layer material.
*Sublimation is a technique used to obtain ultra pure-grade chemicals. For more details about sublimation, please refer to the Sublimed Materials for OLED devices page.
