Used as a metallocene catalyst in olefin polymerization, particularly in the production of polyethylene and polypropylene with controlled molecular weight and narrow polydispersity. Its zirconium center, stabilized by cyclopentadienyl and fluorenyl ligands, enables high catalytic activity and stereoselectivity when activated with methylaluminoxane (MAO) or other co-catalysts. The diphenylmethylidene group enhances thermal stability and influences polymer microstructure, making it suitable for advanced polyolefin materials used in packaging, automotive parts, and specialty films.
