简单介绍


ossila材料B3PyPB  的详细介绍

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.
