This molecule serves as a fundamental building block for advanced materials used in OLED displays and lighting. For procurement managers and R&D scientists, understanding where to buy this compound and its key attributes is essential for project success. As a dedicated manufacturer and supplier, we provide critical insights into this versatile chemical.

Understanding the Chemical Properties and Applications

The Spirobifluorene Diboronate Ester, CAS: 728911-52-2, is distinguished by its unique spiro structure, which confers excellent thermal stability and amorphous film-forming capabilities. These properties are paramount for creating OLED devices with long operational lifetimes and robust performance. The compound’s chemical formula, C37H38B2O4, and molecular weight of 568.32 g/mol, along with a melting point of 332 °C, indicate its stability under processing conditions. The key feature for synthetic chemists are the two boronate ester groups, which readily participate in cross-coupling reactions, most notably Suzuki-Miyaura coupling. This allows for the precise construction of complex organic molecules used in various layers of OLED devices:

  • Electron Transport Layers (ETLs): The spirobifluorene core, when appropriately functionalized via reactions with this intermediate, can create materials with superior electron mobility and injection efficiency, vital for high-performance OLEDs.
  • Host Materials: The high triplet energy and rigidity of spirobifluorene derivatives make them excellent candidates for host materials in phosphorescent OLEDs, contributing to efficient energy transfer and preventing exciton quenching.
  • Hole Transport Layers (HTLs): This intermediate is also used to synthesize robust HTLs that improve charge balance and device stability.
  • Organic Photovoltaics (OPVs): Beyond OLEDs, these boronate esters are explored for use in organic solar cells as components of donor or acceptor materials to enhance efficiency.
