Patent ID: 7847039

Claim:
A transition metal complex represented by the following Chemical Formula I, which has, around a group IV transition metal, a cyclopentadiene derivative and at least one aryl oxide ligand with a heterocyclic aryl derivative substituted at the ortho-position thereof, with no crosslinkage between the cyclopentadiene derivative and the at least one aryl oxide ligand: wherein M is a group IV transition metal in the periodic table; Cp is a cyclopentadienyl ring or a fused ring including a cyclopentadienyl ring, which is η 5 -bonded to the central metal M, wherein the cyclopentadienyl ring or cyclopentadienyl fused ring may be further substituted with (C1-C20) alkyl, (C6-C30) aryl, (C2-C20) alkenyl or (C6-C30) aryl (C1-C20) alkyl; A is a substituent R 1 , R 2 , R 3 , R 4 , R 5 , R 6 , R 7 and R 8 are, independently of each other, hydrogen, (C1-C20) alkyl, (C3-C20) cycloalkyl, (C1-C20) alkyl-substituted or (C6-C30) aryl-substituted silyl, (C6-C30) aryl, (C6-C30) aryl (C1-C10) alkyl, (C1-C20) alkoxy, (C1-C20) alkyl-substituted or (C6-C20) aryl-substituted siloxy, (C1-C20) alkyl-substituted or (C6-C30) aryl-substituted amino, (C1-C20) alkyl-substituted or (C6-C30) aryl-substituted phosphino, (C1-C20) alkyl-substituted mercapto or nitro, wherein the alkyl, aryl or alkoxy group of said R 1 to R 8 may be further substituted with halogen or may form a fused ring together with a neighboring substituent; D is N—R 9 , oxygen or sulfur; R 9 is linear or branched (C1-C20) alkyl, (C6-C30) aryl, (C1-C20) alkyl-substituted or (C6-C30) aryl-substituted silyl; n is an integer 1 or 2; and X is, independently of each other, halogen, (C1-C20) alkyl, (C3-C20) cycloalkyl, (C6-C30) aryl (C1-C20) alkyl, (C1-C20) alkoxy, (C3-C20) alkylsiloxy, (C1-C20) alkyl-substituted or (C6-C30) aryl-substituted amino, (C1-C20) alkyl-substituted or (C6-C30) aryl-substituted phosphino or (C1-C20) alkyl-substituted mercapto.
