B3PyPB, ETL and HBL material in OLED devices
Used to improve the performance of PhOLEDs
Bearing four pyridyl groups, B3PyPB is electron deficient and has high electron mobility. It is widely used as an electron-transport material (ETL) in OLED devices. With a deep HOMO energy level (6.60 eV), B3PyPB is also used as a hole-blocking layer material (EBL).
Having a high triplet energy (ET = 2.77 eV), B3PyPB is used in phosphorescent OLEDs to suppress triplet quenching of the light-emitting molecules, leading to higher external quantum efficiency - hence improving the device performance.
