3TPYMB , Tris(2,4,6-triMethyl-3-(pyridin-3-yl)phenyl)borane Structural

What is 3TPYMB , Tris(2,4,6-triMethyl-3-(pyridin-3-yl)phenyl)borane?

Description

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 , 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.

General Description

Electron transport and hole blocking material in organic light emitting diodes (OLED).
