As a leading OLED intermediate supplier in China, understanding the role and sourcing of this compound is paramount for researchers and procurement managers alike.

Understanding the Key Intermediate: 5-Bromo-7,7-dimethyl-7H-benzo[c]fluorene

With the molecular formula C19H15Br and a molecular weight of approximately 323.23 g/mol, this compound is a brominated derivative of benzo[c]fluorene. Its structure is characterized by a benzo[c]fluorene core, substituted with a bromine atom at the 5-position and two methyl groups at the 7-position. This specific arrangement of functional groups imparts desirable electronic and physical properties, making it an ideal precursor for various layers within an OLED device, including emissive or charge-transport layers.

The presence of the bromine atom, for instance, influences the compound's electron-withdrawing capabilities, which is vital for tuning charge carrier injection and transport. Simultaneously, the methyl groups at the 7-position are known to improve solubility and thermal stability. This balance of properties is essential for ensuring the processability and operational longevity of the final OLED materials. For R&D scientists and procurement specialists looking to buy high-purity C19H15Br for OLED applications, sourcing from a reputable manufacturer is key to achieving consistent results.

Synthesis and Purity: The Foundation of OLED Excellence

The synthesis of 5-Bromo-7,7-dimethyl-7H-benzo[c]fluorene typically involves multi-step processes, often starting from precursors like 1-bromonaphthalene. Optimized synthetic routes, employing catalysts such as Pd(dppf)Cl₂ and ion-exchange resins, are crucial for achieving high yields and purity. The reported purity levels often exceed 98%, which is a critical specification for OLED intermediates. Impurities, even in small amounts, can act as quenching sites or trap charge carriers, significantly degrading device efficiency and lifespan. Therefore, when you buy 5-bromo-7,7-dimethyl-7h-benzo[c]fluorene, ensuring a high purity assay from a reliable supplier is non-negotiable.
