The field of material science constantly seeks novel compounds that can unlock new functionalities and enhance existing technologies. 2-Bromo-1,10-Phenanthroline (CAS 22426-14-8) is one such compound, valued for its distinct physical and chemical properties that make it a critical intermediate, particularly in the development of advanced electronic materials like OLEDs.

Physically, 2-Bromo-1,10-Phenanthroline typically presents as a white to light yellow or orange powder. Its melting point, usually in the range of 161.0 to 165.0 °C, indicates a stable solid form under standard conditions. The molecular weight of approximately 259.10 g/mol and its specific molecular formula (C12H7BrN2) are key identifiers for its purity and identity. These basic physical characteristics are important for handling, storage, and processing in industrial settings.

Chemically, the compound's significance lies in its structure and reactivity. As a derivative of 1,10-Phenanthroline, it inherits the characteristic bidentate coordination behavior, meaning it can bind to metal ions through two nitrogen atoms. This property is fundamental to its use in coordination chemistry, where it forms stable complexes with transition metals. The bromine atom at the 2-position introduces a crucial electronic perturbation. As an electron-withdrawing group, it subtly modifies the electron density on the phenanthroline nitrogen atoms, influencing their basicity and the overall electronic character of the resulting metal complexes. This makes it a valuable tool for tuning the properties of metal-organic frameworks and catalysts.

The synthesis of 2-Bromo-1,10-Phenanthroline is a focus for chemical manufacturers like NINGBO INNO PHARMCHEM CO.,LTD., who aim for high purity to serve the demanding material science applications. Rigorous synthesis and purification protocols are employed to eliminate impurities that could compromise the performance of the final materials. Spectroscopic techniques like NMR and mass spectrometry are vital for confirming the structure and purity, ensuring that the intermediate meets the precise specifications required for advanced applications.

The unique electronic effects of the bromine substituent are particularly relevant for its role in OLED material synthesis. By influencing the energy levels and charge-transport characteristics of molecules, it helps in designing more efficient and stable OLED devices. Furthermore, its reactivity in cross-coupling reactions allows for further functionalization, leading to a wider array of specialized materials with tailored optical and electronic properties. This adaptability makes it a cornerstone in the development of next-generation organic semiconductor materials.

The study of 1,10-Phenanthroline derivatives, including halogenated variants, is an active area of research, continually expanding the toolkit available to material scientists. The precise control over molecular properties offered by compounds like 2-Bromo-1,10-Phenanthroline is essential for innovation in areas ranging from advanced displays to novel catalytic systems, underscoring the importance of electronic chemicals manufacturing.
