This invention relates to compounds represented by formula:
wherein M is a group 3, 4, 5 or 6 transition, lanthanide, or actinide metal atom; E is an indenyl ligand substituted in any position with at least one aromatic or pseudoaromatic heterocyclic substituent that is bonded to the indenyl ring through a nitrogen or phosphorous ring heteroatom; A is a substituted or unsubstituted cyclopentadienyl, heterocyclopentadienyl, indenyl, heteroindenyl, fluorenyl, or heterofluorenyl ligand, or other mono-anionic ligand, or A may, independently, be E; Y is an optional bridging group; y is zero or one; X are, independently, univalent anionic ligands, and provided that when A is E, and y is one, and Y is bonded to the one position of each indenyl ligand, and per indenyl ligand there is only one aromatic heterocyclic or pseudoaromatic heterocyclic that is bonded to the indenyl ligand.
本发明涉及以下式表示的化合物:
其中,M是3、4、5或6族过渡金属、镧系金属或锕系金属原子;E是任何位置上至少带有一种芳香或伪芳香杂环取代基的茚基配体,该取代基通过氮或磷杂环原子与茚环相连;A是取代或未取代的环戊二烯基、杂环戊二烯基、茚基、杂茚基、芴基或杂芴基配体,或其他单阴离子配体,或A可以独立地是E;Y是可选的桥接基团;y为零或一;X是独立的一价阴离子配体,且当A为E,y为一,并且Y与每个茚基配体的一位置相连时,每个茚基配体仅与一个芳香杂环或伪芳香杂环相连。
