Usage

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.

Method for Preparation Metal Compounds of 8-Hydroxyquinoline or Derivatives

This invention, which involves “the preparation method of 8-hydroxyquinoline metallic compound”, is a synthetic method of organic electroluminescent materials. The preparation method of compound Mqnqm′ is to add solution prepared by Zengshui solvent and industrial ligand into reaction vessel, stir it at a certain temperature, and then achieve high-purity product, as for the Mqnqm′, M stands for Al, Li, n stands for 1-3, m is 0-2, q is 8-hydroxyquinoline and its derivatives, and q′ is ligand different from q. Zengshui solvent is adopted in this invention which can react effectively and thus reducing reaction time and avoiding cumbersome operation and the refining process; this invention also increases total yield and purity, the mother liquor obtained can be recycled, which reduces environment pollution and cost as well. This technology can also spread to the preparation of other 8-hydroxyquinoline metallic compound and the product achieved can be used as electroluminescent materials or electron-transport materials.
