Abstract: The present disclosure provides a preparation method of a homogeneous rare earth catalyst. In the present disclosure, a depolymerizing agent is introduced into the homogeneous rare earth catalyst to promote complete depolymerization of an alkyl aluminum trimer into monomolecular alkyl aluminum. As a result, there is an increase in the number of the alkyl aluminum which serves as an effective chain transfer agent, resulting in a greatly improved chain transfer rate, such that a polymerization system has completed the chain transfer in an early stage of the reaction. Accordingly, an aluminum terminal molecular chain has an increased concentration, leading to an accelerated exchange with an active center propagating chain and a decreased influence caused by an increased viscosity of the system, maintaining living polymerization of the system.

Abstract: Disclosed is a preparation method and application of an imidazole-functionalized metal-organic framework material, Im@RE-MOF, with a lipase-mimetic catalytic activity. The method introduces an imidazole group into a benzene tricarboxylic acid framework through acyl chlorination and Friedel-Crafts acylation reactions to prepare an imidazole-functionalized organic ligand, and the functionalized ligand is self-assembled with a rare earth or transition metal ion (RE=Zr, Sc, or Cd) by a solvothermal method to obtain a target product Im@RE-MOF. The enzyme-mimetic material effectively mimics the catalytic center of natural lipase due to the regular pore structure of the MOF and the catalytic activity of the imidazole group.
