Material science is a field driven by innovation, constantly seeking novel compounds to enable next-generation technologies. Within the realm of organic electronics, especially OLED displays, the precise synthesis of functional organic molecules is paramount. For researchers and product formulators, understanding the properties and applications of specific chemical intermediates is key to success. This article delves into the utility of (4-Bromo-1-naphthyl)boronic acid (CAS: 145965-14-6), a critical component in modern material science, particularly within the OLED industry.

Understanding (4-Bromo-1-naphthyl)boronic Acid

(4-Bromo-1-naphthyl)boronic acid is a white crystalline powder with a defined melting point range of 230-260°C. Its chemical structure combines a naphthalene ring system, which is known for its electron-rich properties and ability to facilitate charge transport, with a bromine atom and a boronic acid functional group. This unique combination makes it an exceptionally useful synthon in organic chemistry. The boronic acid moiety readily participates in palladium-catalyzed cross-coupling reactions, such as the Suzuki-Miyaura coupling, which is widely used to form carbon-carbon bonds. The bromine atom serves as a reactive site for further functionalization or as a handle for subsequent coupling reactions, allowing for the construction of complex conjugated systems.

Key Role in OLED Technology

The primary application of (4-Bromo-1-naphthyl)boronic acid is as an intermediate in the synthesis of OLED materials. These materials are the heart of OLED displays, responsible for emitting light when an electric current is applied. The specific structure of this boronic acid allows it to be incorporated into polymers or small molecules designed to act as emitters, hosts, or charge transport layers. By using high-purity intermediates (typically >97%), material scientists can ensure that their synthesized compounds exhibit the desired electronic and optical properties, leading to improved device efficiency, color purity, and operational lifetime. When you are looking to buy this intermediate, consider its role in creating materials that enhance charge injection, transport, and recombination within the OLED device.

Sourcing Strategies for R&D and Production

For professionals in research and development or manufacturing, procuring (4-Bromo-1-naphthyl)boronic acid requires identifying reliable suppliers. Leading manufacturers, often based in China, specialize in producing these high-purity intermediates. When seeking to purchase, it is beneficial to look for suppliers who explicitly state the CAS number (145965-14-6) and the guaranteed minimum purity. Furthermore, inquire about product availability, packaging options (e.g., 25g, 100g, bulk), and pricing for various quantities. Many suppliers are happy to provide samples for initial testing, which is a vital step in validating the material for your specific synthesis pathways.

In essence, (4-Bromo-1-naphthyl)boronic acid represents a critical chemical intermediate that empowers advancements in material science. Its versatile reactivity and inherent electronic properties make it a go-to compound for OLED material synthesis. By carefully selecting your supplier and prioritizing quality, you can ensure the success of your innovative material development projects.
