Used as a ligand in coordination chemistry, particularly in catalysis. Its sterically hindered structure enhances stability in metal complexes, making it effective in homogeneous catalysts for cross-coupling reactions and polymerization processes. Commonly employed with palladium, nickel, and iron complexes to improve catalytic activity and selectivity. Also applied in the development of luminescent materials and sensors due to its ability to form stable complexes with lanthanides and transition metals. Useful in organic synthesis where controlled reactivity and robust metal-ligand frameworks are required.
