What is 2,2'-(1,3-Phenylene)bis[5-(4-tert-butylphenyl)-1,3,4-oxadiazole]?
Description
1,3-bis[2-(4-tert-butylphenyl)-1,3,4-oxadiazo-5-yl]benzene (OXD-7) is a well known electron-transporting material due to?the?electron-accepting?property of?the oxadiazole units. Together with poly(9-vinylcarbazole) (PVK, electron donating), OXD-7 (electron withdrawing) is the most widely used hybrid-type host due to its good solubility and film morphology by the bulky tert-butyl units.
