BTB, a triazine compound, namely 4,4'-bis(4,6-diphenyl-1,3,5-triazin-2-yl)biphenyl, is used as an electron-transport material in organic light-emitting devices (OLEDs) due to its electron deficiency from the two triazine units.
With electron mobility greater than 10−4 cm2V−1 s−1, BTB demonstrates an electron mobility 10-fold greater than that of the widely-used material tris(8-hydroxyquinoline) aluminum (Alq3). OLEDs incorporating BTB as the electron transport layer exhibit lower driving voltages and higher efficiencies - relative to those incorporating Alq3.
BTB, like other electron-deficient materials (such as T2T), can be used as a phosphorescent host material for green and red light-emitting diodes.
