Used as a key intermediate in organic synthesis, particularly in the preparation of luminescent metal complexes for OLEDs and other optoelectronic devices. Its silyl-protected ethynyl groups allow for selective coupling reactions, enabling the construction of conjugated systems in supramolecular chemistry. Also employed in catalysis, where it acts as a ligand to stabilize transition metal centers in cross-coupling reactions. The compound’s rigid phenanthroline backbone enhances metal ion chelation, making it useful in sensor design for detecting metal ions in solution. Additionally, it serves in materials science to modify surface properties of nanomaterials and in the development of molecular wires and organic semiconductors.
