| Classification | Electron transporting materials, Hole blocking materials, Light emitter layer materials, Phosphorescent host materials, Organic light-emitting diodes, Organic electronics, Sublimed materials.
| | Applications | Bis(8-hydroxy-2-methylquinoline)-(4-phenylphenoxy)aluminum, known as BAlq or BAlq3, is widely used as blue-emitting layer materials in organic light-emitting diodes. It is also used as hole-blocking layer or as a “barrier-softening” interfacial layer in between the electron transporting and emissive layers.
BAlq is also applied as the host material and electron-transport type hole-blocking layer in red PHOLEDs, and to improve the efficiency and lifetime of PHOLEDs. As a hole-blocking material, it is known to allow for high lifetimes, up to 160,000 hours at a luminance level of 100 cd/m2.
BAlq has a glass transition temperature of 99 °C and is photochemically stable.
