简单介绍


ossila材料BAlq  的详细介绍

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 [1, 2, 3, 4].

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 [3].

BAlq has a glass transition temperature of 99 °C and is photochemically stable [5].
