Silicon-bridged metallocene complex with C2 symmetrical structure and application thereof

The invention relates to a preparation method and application of an olefin polymerization reaction catalyst, in particular to a silicon-bridged metallocene complex with a C2 symmetrical structure andapplication thereof. Molecules of the silicon-bridged metallocene complex with the novel C2 symmetric structure in the invention contain seven different ligand structures, and ligands have chemical groups with different electron donating capacities, so different chemical environments are provided for a metal center, and the metallocene complex with the novel structure is constructed. By changing askeleton structure and substituent groups, the three-dimensional effect and the electronic effect of the metallocene complex can be conveniently regulated and controlled, so the catalytic performanceis regulated and controlled, and polyolefin high polymer materials with different structures and properties are prepared. 本发明涉及一类烯烃聚合反应催化剂的制备方法与应用，特别涉及一种C2对称结构的硅桥联茂金属配合物及其应用，本发明所设计的新型C2对称结构硅桥联茂金属配合物分子中含有七种不同的配体结构，配体上具有供电子能力不同化
