Used in the synthesis of metal-organic frameworks (MOFs) due to its ability to act as a rigid, iodine-functionalized linker. The iodine atoms enhance heavy atom content, making the resulting MOFs suitable for applications in X-ray contrast agents and radiation shielding materials. Also employed in covalent organic frameworks (COFs) for optoelectronic devices, where the iodine substituents facilitate post-synthetic modifications through cross-coupling reactions. Its high density and polarizability improve performance in gas adsorption studies, particularly for heavy gases like CO₂ and Xe. Additionally, it serves as a precursor in the preparation of luminescent materials and coordination polymers with nonlinear optical properties.
