In the intricate world of organic synthesis, particularly within the demanding sector of electronic materials, the precise chemical properties of intermediates dictate the success of the final product. This article explores 4'-bromo-10-phenyl-10H-spiro[acridine-9,9'-fluorene] (CAS 1598410-12-8), a key intermediate whose unique structure and reactivity are vital for advancing technologies like OLEDs. We will examine its characteristics and its significance when sourced from manufacturers.

Chemical Profile: 4'-Bromo-10-phenyl-10H-spiro[acridine-9,9'-fluorene]

The molecular formula for this compound is C31H20BrN, with a molecular weight of approximately 486.40 g/mol. The presence of a bromine atom on the fluorene moiety makes it amenable to various coupling reactions, such as Suzuki, Stille, or Buchwald-Hartwig couplings, which are fundamental in building complex organic molecules. The spirocyclic framework, where the acridine and fluorene units are linked via a spiro junction, imparts rigidity and a non-planar geometry. This three-dimensional arrangement is often beneficial in preventing aggregation and improving the amorphous nature of organic thin films used in electronic devices, thereby enhancing their stability and efficiency.

Role in Organic Synthesis for OLEDs

As an intermediate, 4'-bromo-10-phenyl-10H-spiro[acridine-9,9'-fluorene] serves as a versatile precursor for synthesizing a wide array of advanced materials for OLEDs. Its bromine substituent acts as a reactive handle, allowing chemists to attach other functional organic groups. These modifications are critical for fine-tuning the electronic and optical properties, such as:

  • Host Materials: Its rigid structure can create effective hosts for phosphorescent emitters, improving triplet energy transfer and device efficiency.
  • Charge Transport Layers: Derivatives can be synthesized to possess excellent electron or hole mobility, facilitating efficient charge injection and transport within the OLED structure.
  • Emissive Materials: By functionalizing the core structure, new emitters with desired colors and high photoluminescence quantum yields can be developed.

Researchers and development teams often seek to 'buy' this intermediate from reliable manufacturers, valuing consistency and purity (typically 97% min) to ensure predictable outcomes in their synthesis procedures. Understanding the 'price' and the supplier's capabilities is important for cost-effective R&D.

Sourcing from Manufacturers

When procuring this specialized chemical, partnering with experienced manufacturers, especially those based in China with strong R&D capabilities, is advisable. They can often provide detailed technical specifications, certificates of analysis, and the scalability required for larger projects. Ensuring a stable supply of high-quality intermediates like CAS 1598410-12-8 is a cornerstone of successful material development in the competitive field of organic electronics.

In summary, the chemical properties of 4'-bromo-10-phenyl-10H-spiro[acridine-9,9'-fluorene] make it an indispensable intermediate for creating next-generation OLED materials. Its strategic use in organic synthesis, coupled with reliable sourcing, is key to innovation.
