The field of organic electronics is propelled by the precise engineering of molecular structures, and within this domain, 4,4'-Dibromotriphenylamine has carved out a significant niche. As a vital OLED intermediate, understanding its chemical properties is fundamental to appreciating its utility and the advanced applications it enables. From its physical characteristics to its reactivity, this compound is a testament to the sophisticated chemistry underpinning modern display and lighting technologies.

Key to the value of 4,4'-Dibromotriphenylamine are its precisely defined physical and chemical properties. With a molecular formula of C18H13Br2N and a molecular weight of 403.11100, it possesses a specific structure that is crucial for its function. Its density, measured at 1.593 g/cm³, and a melting point of 69°C indicate its solid state under typical ambient conditions. The boiling point of 470.728°C and a flash point of 110°C provide further insight into its thermal stability and handling requirements. The index of refraction at 1.679 is also a notable characteristic, particularly relevant in optoelectronic applications. These parameters, supplied by manufacturers like NINGBO INNO PHARMCHEM CO.,LTD., are critical for process design and quality control.

The primary application of 4,4'-Dibromotriphenylamine is as an intermediate in the synthesis of organic light-emitting diodes (OLEDs). In this context, it is used to create materials that facilitate the efficient transport of charge carriers (holes and electrons) and the emission of light. The triphenylamine core is known for its electron-donating properties, making it an excellent scaffold for developing hole-transporting materials. The strategically placed bromine atoms allow for further functionalization, enabling the precise tuning of electronic band gaps and charge mobilities. This makes it invaluable for achieving optimal performance in OLED devices, where even minor variations in intermediate purity can significantly impact device efficiency and longevity. Securing a consistent supply of this compound with a purity of ≥99.0% is therefore a primary concern for companies in this sector.

Beyond its direct use in OLEDs, 4,4'-Dibromotriphenylamine can also serve as a building block for other advanced organic electronic materials, including those used in organic photovoltaics (OPVs) and organic field-effect transistors (OFETs). Its molecular structure offers a versatile platform for researchers exploring new frontiers in organic semiconductor design. The ability to purchase this chemical from trusted suppliers like NINGBO INNO PHARMCHEM CO.,LTD., who can also provide detailed specifications and support, is essential for research and development efforts. The price and availability of such specialized chemicals are key considerations for scaling up production and commercialization.

In conclusion, 4,4'-Dibromotriphenylamine is more than just a chemical compound; it is an enabler of cutting-edge technology. Its well-defined chemical properties and its role as a versatile OLED intermediate underscore its importance in the advancement of organic electronics. By understanding and leveraging its characteristics, manufacturers and researchers can continue to push the boundaries of what is possible in display and lighting innovation.
