Patent ID: 7834204

Claim:
A transition metal compound represented by the following general formula [III]: wherein R 23 , R 24 , R 25 , R 26 , R 27 , and R 28 are each independently selected from hydrogen, a hydrocarbon group, a silicon-containing group, a sulfur-containing group, an oxygen-containing group, a nitrogen-containing group, and a halogen-containing group, adjacent substituents of R 23 to R 28 are optionally bonded to each other to form a ring, M is a Group 4 transition metal, Y is carbon atom, Q is selected from halogen, a hydrocarbon group, an anionic ligand and a neutral ligand capable of coordinating with a lone electron pair, which is selected in the same combination or different combination, j is an integer of 1 to 4, and Z is selected from a fluorenylidene group having a free valency of divalence, which is derived by removing R 1 and R 2 from the fluorene derivative represented by the general formula [I] wherein R 1 , R 2 , R 3 , R 5 , R 6 , R 7 , R 8 , R 9 , R 10 , R 11 , R 12 , and R 14 are each independently selected from hydrogen, a hydrocarbon group and a silicon-containing group, R 4 and R 13 are each independently selected from hydrogen, a hydrocarbon group, a silicon-containing group, a sulfur-containing group, an oxygen-containing group, a nitrogen-containing group, and a halogen-containing group, adjacent substituents of R 1 to R 14 are optionally bonded to each other to form a ring, R 4 and R 5 are optionally joined together to form Ra which is a divalent substituent, R 12 and R 13 are optionally joined together to form Rb which is a divalent substituent, wherein Ra and Rb are each a divalent substituent other than a vinylene group, which is selected from a hydrocarbon group, a silicon-containing group, a sulfur-containing group, an oxygen-containing group, a nitrogen-containing group, and a halogen-containing group; or a fluorenylidene group having a free valency of divalence, which is derived by removing two hydrogen atoms at the 10-position of the fluorene derivative of general formula [II]: wherein R 15 , R 16 , R 17 , R 18 , R 19 , R 20 , R 21 , and R 22 are each independently selected from hydrogen, a hydrocarbon group, a silicon-containing group, a sulfur-containing group, an oxygen-containing group, a nitrogen-containing group, and a halogen-containing group; or wherein R 15 , R 16 , R 18 , R 19 , R 21 , and R 22 are each a methyl group, and R 17 and R 20 are each hydrogen.
