The field of organic electronics, particularly OLED technology, relies on a sophisticated array of chemical compounds to achieve its remarkable display and lighting capabilities. Understanding the chemistry behind these materials, including their synthesis and application, is crucial for R&D scientists and procurement managers. This article delves into 4,6-Dibromodibenzofuran (CAS 201138-91-2), a key organic intermediate whose unique properties make it indispensable in the creation of high-performance electronic materials.

Understanding 4,6-Dibromodibenzofuran

4,6-Dibromodibenzofuran is a dibenzofuran derivative characterized by its molecular formula C12H6Br2O and a molecular weight of approximately 325.98. It typically presents as an off-white powder, with a guaranteed purity of ≥99.0% from reputable manufacturers. The compound’s physical properties, such as its melting point (around 147-151 °C) and boiling point (around 396 °C), indicate stability under standard handling conditions but also require consideration during high-temperature synthesis processes. Its primary value lies in its role as an intermediate in complex organic synthesis, especially within the photoelectric and electronics industries.

Synthesis Pathways and Manufacturing Considerations

While specific proprietary synthesis routes may vary among manufacturers, the production of 4,6-Dibromodibenzofuran generally involves the selective bromination of dibenzofuran. The precise control of reaction conditions, including temperature, reaction time, and the molar ratio of reactants, is critical to achieve the desired 4,6-dibromo substitution pattern and high purity. Manufacturers in China are particularly adept at optimizing these processes, leveraging their expertise in fine chemical synthesis to produce this intermediate efficiently and cost-effectively. When considering purchasing this compound, looking for suppliers with robust R&D capabilities and stringent quality control measures is advisable. These manufacturers are typically equipped to handle both pilot-scale and large-scale production, ensuring a consistent supply for your needs. Asking about the manufacturing process and the supplier's commitment to quality assurance can provide valuable insights.

Applications in Photoelectric Synthesis and OLED Materials

The most significant application of 4,6-Dibromodibenzofuran is its use as a precursor in the synthesis of materials for OLED devices. The dibenzofuran backbone offers thermal stability and good electronic properties, while the bromine atoms serve as reactive handles for introducing other functional groups via palladium-catalyzed cross-coupling reactions. This allows for the construction of highly tailored organic semiconductor molecules that are essential for:

  • Host materials: Providing a stable matrix for emissive dopants.
  • Charge transport materials: Facilitating the movement of electrons and holes within the device.
  • Emitting materials: Directly contributing to the light emission process.

These synthesized materials are critical for developing OLED displays that exhibit improved efficiency, reduced power consumption, and enhanced color rendering. The demand for such high-performance intermediates continues to grow as the OLED market expands into new applications like flexible screens, wearable technology, and automotive lighting.

Where to Buy and Inquire for Quotes

For procurement professionals and researchers looking to buy 4,6-Dibromodibenzofuran, identifying reliable manufacturers and suppliers is key. Online chemical directories and B2B platforms often list suppliers with detailed product information, including CAS numbers, specifications, and contact details. When you find a potential supplier, do not hesitate to request a formal quote, specifying your required quantity. Discussing sample availability is also recommended to evaluate the product's quality firsthand. Partnering with experienced suppliers, especially those in China known for their expertise in fine chemicals and OLED intermediates, can ensure you receive a high-purity product at a competitive price, directly supporting your critical research and manufacturing endeavors.
