In the intricate world of material science, the precise design and synthesis of molecules are key to unlocking new functionalities and performance characteristics. 2-Bromophenanthrene, identified by its CAS number 62162-97-4, is a compound that has garnered significant attention for its role as a versatile intermediate in the development of advanced materials, particularly in the realm of organic electronics. This article aims to shed light on the scientific importance of 2-Bromophenanthrene, its key properties, and its applications, offering insights for researchers and scientists working at the forefront of material innovation.

The molecular structure of 2-Bromophenanthrene is central to its utility. It consists of a phenanthrene core – a tricyclic aromatic hydrocarbon – functionalized with a bromine atom at the second position. This specific arrangement imparts several valuable characteristics. The extended pi-electron system of the phenanthrene moiety contributes to favorable electronic and optical properties, making it an attractive component for conjugated organic materials. The bromine atom, being an excellent leaving group, facilitates a wide array of synthetic transformations. This includes various palladium-catalyzed cross-coupling reactions (e.g., Suzuki, Heck, Sonogashira), which are indispensable tools for constructing complex organic molecules with specific architectures and functionalities. The ability to precisely control the introduction of other molecular fragments via these coupling reactions makes 2-Bromophenanthrene a key building block for molecular engineers.

The primary application driving the demand for 2-Bromophenanthrene is its role as an intermediate in the synthesis of materials for Organic Light-Emitting Diodes (OLEDs). In OLED technology, organic molecules are engineered to emit light when an electric current is applied. The efficiency, color, and lifespan of these devices are heavily dependent on the molecular design of the organic layers. 2-Bromophenanthrene serves as a crucial precursor for creating host materials, emissive dopants, and charge-transporting molecules that form these critical layers. Researchers leverage its structure to build larger, more complex conjugated systems that exhibit the desired photophysical properties for high-performance displays and lighting.

Beyond OLEDs, the synthetic flexibility offered by 2-Bromophenanthrene extends its utility to other areas of material science. It can be employed in the synthesis of organic semiconductors for applications in organic field-effect transistors (OFETs) and organic photovoltaics (OPVs). Its structure can also be incorporated into fluorescent probes for bio-imaging or sensing applications, or used to develop novel catalysts and advanced polymers. The pursuit of materials with tailored electronic, optical, and structural properties frequently leads researchers back to versatile intermediates like 2-Bromophenanthrene.

For scientists aiming to purchase 2-Bromophenanthrene, ensuring high purity (often ≥99.0%) is paramount to guarantee the integrity of their research outcomes. Sourcing from reputable chemical suppliers, particularly those specializing in fine chemicals and intermediates for material science, is essential. These suppliers can provide the necessary quality documentation and ensure a consistent supply chain, allowing researchers to focus on their scientific endeavors. Understanding the CAS number 62162-97-4 is the first step in identifying and procuring this valuable molecular tool.
