In the realm of advanced materials, 8-Hydroxyquinoline aluminum salt, widely recognized as Alq3 (CAS 2085-33-8), stands out for its significant contributions to the field of organic electronics, particularly in OLED technology. For procurement managers and R&D scientists, understanding the detailed properties and application scope of Alq3 is key to effective sourcing and integration into product lines. This article provides a comprehensive overview for those looking to buy Alq3.

Chemical Identity and Specifications

Alq3, chemically designated as Tris(8-hydroxyquinoline)aluminum, is an organometallic compound with the molecular formula C27H18AlN3O3. Its physical form is typically a yellow powder, and it is characterized by a high melting point (often exceeding 300°C) and good solubility in organic solvents like chloroform and THF. A critical specification for its use in high-performance electronic devices is its purity, with many manufacturers offering grades of 98% or even higher (e.g., sublimed grade >99.9%). When sourcing, pay close attention to the CAS number 2085-33-8 to ensure you are obtaining the correct compound.

Key Applications of Alq3

The primary application of Alq3 lies in its use as an electron transport material (ETM) and emissive layer material (ELM) in Organic Light-Emitting Diodes (OLEDs). Its electron mobility and suitable energy levels facilitate efficient charge injection and transport, crucial for device operation. Alq3 is known for its green luminescence, contributing to the color palette of OLED displays. Beyond OLEDs, it also finds utility as a metal corrosion inhibitor in certain synthetic processes within the pharmaceutical and agricultural chemical sectors.

Why Purchase Alq3 from a Specialized Manufacturer?

For optimal performance in demanding electronic applications, the quality of Alq3 is paramount. Sourcing from specialized manufacturers ensures access to materials processed to meet stringent electronic-grade standards. These manufacturers often employ advanced purification techniques like sublimation, which removes trace impurities that can otherwise hinder electron transport or cause device degradation. Therefore, when you buy Alq3, opting for a supplier that guarantees high purity and consistent batch-to-batch quality is a strategic advantage.

Sourcing Strategies and Price Points

When seeking to buy 8-Hydroxyquinoline Aluminum Salt, it is advisable to engage with established chemical suppliers and manufacturers, especially those with a strong presence in the electronic chemicals market. Requesting detailed quotes for bulk purchases can reveal significant cost savings. Factors influencing the price include the purity grade, order volume, and geographical origin of the manufacturer. Exploring options from leading manufacturers in regions like China can offer a balance of quality and cost-effectiveness for your sourcing needs.

Conclusion

8-Hydroxyquinoline Aluminum Salt (Alq3) is a versatile and indispensable material for the advancement of organic electronics. Its effectiveness as an electron transport and emissive layer component in OLEDs, coupled with its niche applications as a corrosion inhibitor, underscores its importance. For those looking to buy Alq3, careful consideration of purity, application requirements, and supplier reputation will ensure the acquisition of a high-quality product essential for technological innovation.
