Application

3,8-Dibromo-1,10-phenanthroline serves as a key building block for synthesizing photoactive metal-organic frameworks (MOFs) and coordination polymers. Its electron-withdrawing bromine substituents modify the electronic properties of phenanthroline-based ligands, enabling fine-tuning of emission spectra in luminescent materials. The compound is also employed in cross-coupling reactions (e.g., Suzuki-Miyaura) to construct extended π-conjugated systems for organic electronics. In catalysis, it acts as a chelating agent for palladium and copper complexes in C-C bond-forming reactions.
