Heteroatom-containing π-ligand metallocene complex, method for producing the same, catalyst system thereof and application of catalyst system

摘要

The invention relates to a metallocene complex with a heteroatom-containing π-ligand and a preparation method therefor, a catalyst system containing the same and use thereof. The metallocene complex has the structure represented by chemical formula (I): M is a transition metal selected from group 3, 4, 5 or 6 of the Periodic System of the Elements, including lanthanides and actinides; each X is same or different, selected from hydrogen, halogen, alkyl R, alkoxyl OR, mercapto SR, carboxyl OCOR, amine group NR2, phosphine group PR2、-OR°O- and OSO2CF3; n is an integer from 1 to 4 and n is not zero; the product of the charge of n and X equals the charge of the central metal atom M minus 2; Q is a bivalent radical; A is aπ-ligand; and Z is aπ-ligand.
