For procurement specialists and R&D scientists in the rapidly evolving field of organic electronics, identifying and sourcing high-purity chemical intermediates is a critical task. Among the array of essential materials, N,N-Bis(biphenyl-4-yl)-4'-bromo-biphenyl-4-amine (CAS: 728039-63-2) stands out as a key component for the development of advanced Organic Light-Emitting Diodes (OLEDs). This guide aims to equip buyers with the necessary knowledge to effectively source this vital compound, focusing on specifications, applications, and manufacturer selection.

Understanding the Product: N,N-Bis(biphenyl-4-yl)-4'-bromo-biphenyl-4-amine

This specialized aromatic amine derivative is characterized by its complex structure, which is instrumental in its function within OLED devices. Its high molecular weight (552.502) and specific arrangement of biphenyl and brominated biphenyl units contribute to excellent charge transport capabilities and thermal stability. The product typically presents as a white to off-white powder, with purity levels often specified at ≥99.0%. This high degree of purity is indispensable, as even trace impurities can compromise the performance and lifespan of sensitive OLED components. The bromine substituent also offers a strategic point for further chemical modifications, allowing for tailored material properties.

Key Applications in OLED Technology

The primary application of N,N-Bis(biphenyl-4-yl)-4'-bromo-biphenyl-4-amine lies in its role as an intermediate for synthesizing advanced organic materials used in OLED displays and lighting. It is frequently employed in the creation of host materials for phosphorescent emitters, as well as in hole transport layers (HTLs). These layers are crucial for efficiently injecting and transporting charge carriers (holes) to the emissive layer, where light is generated. The compound’s thermal and morphological stability also contributes to the overall durability and reliability of the final OLED device. Researchers also utilize it for developing novel materials for organic photovoltaics (OPVs) and other organic electronic applications.

Criteria for Selecting a Manufacturer or Supplier

When seeking to buy this intermediate, several factors should guide your selection of a manufacturer or supplier:

  1. Purity and Specifications: Always verify the product's assay (e.g., ≥99.0%), physical appearance, and CAS number (728039-63-2). Reputable manufacturers will readily provide Certificates of Analysis (CoAs).
  2. Production Capacity and Reliability: Ensure the supplier can meet your volume requirements and has a stable production capacity to avoid supply chain disruptions.
  3. Technical Support: A knowledgeable supplier can offer valuable insights into the product's application and handling, acting as a technical partner.
  4. Pricing and Packaging: Obtain quotes for your required quantities and inquire about packaging options (e.g., 25 kg/drum or customized). Competitive pricing from manufacturers in China is often a key consideration.
  5. Quality Management Systems: Look for suppliers with robust quality management systems in place to guarantee consistent product quality.
