The present disclosure provides a compound, a complex, a preparation method thereof, and a use thereof. The compound is represented by the following structural formula, in which R1 to R10 are the same or different and are each independently selected from hydrogen, a hydrocarbon group having a carbon number of C1 to C16, a substituted hydrocarbon group, an alkoxy group, an alkylthio group, an alkylamino group, a haloalkylthio group, a halogen-substituted alkoxy group, a halogen-substituted alkylamino group, an aryloxy group, an arylthio group, an arylamino group, a diphenylphosphino group, a halogen group, a nitro group, or a nitrile group. The complex of one embodiment of the present disclosure has a high catalytic effect, and can be used to prepare a highly branched, controllable, low molecular weight polymer with a high activity. |
