TmPyPB

TmPyPB, ETL/HBL material for organic electronic devices

Blended with TCTA to fabricate high-efficiency blue PHOLEDs

With a low-lying HOMO, high triplet energy level, and electron-deficient pyridine groups, TmPyPB is widely used as an electron-transport layer and hole-blocking layer material in organic electronic devices (such as OLEDs, OPV and perovskite solar cells).

Blending with a hole-transporting material such as TCTA, TmPyPB has been used as a co-host material to fabricate high-efficiency blue PhOLEDs.

TmPyPB, 1,3,5-Tris(3-pyridyl-3-phenyl)benzene from Ossila was used in the high-impact paper (IF 30.85), Rivers of Light—Ternary Exciplex Blends for High Efficiency Solution-Processed Red Phosphorescent Organic Light Emitting Diodes, J. Saghaei, et al., Adv. Funct. Mater., 2108128 (2021); 10.1002/adfm.202108128.
