3TPYMB, an excellent ETL material which allows efficient electron injection
High-purity (>99.0%) and available online for priority dispatch
Tris(2,4,6-trimethyl-3-(pyridin-3-yl)phenyl)borane (known as 3TPYM) is an excellent electron-transport material. With a LUMO energy level of 3.3 eV [1], just lower than most of the work function of cathodes (i.e. CsF/Al), it allows efficient electron injection. This prevents extra electrons from accumulating at the interface.
3TPYMB is also a hole-blocking material with high HOMO of 6.80 eV [1]. This is high enough to block the holes from being recombined with the electrons at the cathode.
3TPYMB has a high triplet-excited energy level (ET = 2.95 eV) [3].
