The performance of cutting-edge display technologies, such as OLEDs, is intricately linked to the chemical and physical properties of the organic materials used in their construction. 2-Bromo-9,10-bis(2-naphthalenyl)anthracene, a key OLED intermediate with CAS number 474688-76-1, is a prime example of a compound engineered for specific electronic functions. Understanding its detailed properties is crucial for researchers and manufacturers aiming to optimize OLED device design and efficiency.

From a chemical standpoint, 2-Bromo-9,10-bis(2-naphthalenyl)anthracene is characterized by its molecular formula C34H21Br and a molecular weight of approximately 509.43500 g/mol. As an anthracene derivative, it possesses a rigid, planar core structure that is well-suited for charge transport and light emission. The strategic placement of the bromine atom and the two naphthalene groups significantly influences its electronic energy levels and molecular packing in thin films. These attributes are fundamental to its role in creating efficient charge injection, transport, and recombination zones within an OLED device. The stability imparted by the aromatic rings and the bromine substituent is key to the long operational life expected from modern electronic displays.

Physically, the compound is typically described as an off-white crystal, a visual indicator of its high purity. This purity is essential; even minor contaminants can act as charge traps or quenchers, drastically reducing the efficiency and lifespan of the OLED. The thermal properties are also highly significant. With a reported boiling point around 630.082ºC and a flash point of 322.452ºC, 2-Bromo-9,10-bis(2-naphthalenyl)anthracene demonstrates considerable thermal stability. This characteristic is vital for the vacuum deposition processes commonly used in OLED manufacturing, where materials are subjected to high temperatures. The refractive index of 1.768 further points to its optical relevance, influencing how light interacts within the device layers.

The application of this naphthalene substituted anthracene compound is primarily as an intermediate in the synthesis of more complex OLED materials. Its structure allows for further chemical modifications, enabling chemists to fine-tune the electronic and optical properties of the final emissive or transport layers. For those looking to purchase 2-Bromo-9,10-bis(2-naphthalenyl)anthracene, it is imperative to source from reputable manufacturers in China, like Ningbo Inno Pharmchem Co., Ltd., who can guarantee adherence to stringent purity and property specifications. This ensures that the material will perform as expected in demanding electronic applications, contributing to breakthroughs in display technology and solid-state lighting.

In essence, the detailed chemical properties of 2-Bromo-9,10-bis(2-naphthalenyl)anthracene make it an indispensable component for advancing OLED technology. Its purity, thermal stability, and electronic characteristics are directly translated into the superior performance of the devices it helps create.
