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.
