简单介绍


ossila材料BPy-OXD  的详细介绍

BPy-OXD is a bipyridyl-substituted oxadiazole derivative with a symmetrical chemical structure of two bipyridyl oxadiazole units being attached on a benzene ring at meta-positions.

Due to the electron deficient nature of both bipyridine and oxadiazole, BPy-OXD has excellent electron accepting, electron transporting, and hole blocking abilities. It also exhibits electrical operation durability with a high glass transition temperature (Tg = 106 ℃). The electron mobility in the vacuum-deposited films of Bpy-OXD is 30 times higher than that of OXD-7.

Compared to OXD-7, which has bulky tert-butyl terminals, BPy-OXD is completely planar due to the intramolecular H---N hydrogen bonding. This leads to significantly large anisotropy of molecular orientation in the film.

BPy-OXD can also be used with electron donating materials, i.e. m-MTDATA, to form exciplexes as active emitting layer materials for highly efficient OLED devices.
