For chemists and materials scientists involved in the development of organic electronic devices, understanding the intrinsic properties and synthesis routes of key intermediates is fundamental. 10,10'-Dibromo-9,9'-bianthryl (CAS: 121848-75-7) stands out as a particularly important compound, serving as a versatile building block in the creation of high-performance OLED and OPV materials.

The molecular formula C28H16Br2 and a molecular weight of approximately 512.24 g/mol characterize this compound. Physically, it typically appears as a white powder. Its melting point, recorded between 357-359°C, indicates a high degree of thermal stability, a crucial characteristic for materials used in electronic applications that can experience elevated temperatures during operation or fabrication. Other reported properties, such as a density of 1.583 g/cm3 and a high flash point of 361.42°C, further underscore its suitability for industrial handling and processing.

The presence of two bromine atoms on the bianthryl core is the cornerstone of its synthetic utility. These halogen substituents serve as excellent leaving groups, readily participating in various palladium-catalyzed cross-coupling reactions. For instance, reaction with arylboronic acids (Suzuki coupling) or amines (Buchwald-Hartwig amination) allows for the regioselective introduction of diverse functional groups. This capability is essential for chemists to tailor the electronic and optical properties of the final materials, optimizing them for specific roles within an OLED device, such as emissive layers or charge transport layers.

The synthesis of 10,10'-Dibromo-9,9'-bianthryl typically involves the bromination of 9,9'-bianthracene or related precursors. Achieving high purity, often exceeding 97%, is critical and requires careful control of reaction conditions and purification techniques.
