  • Heterobimetallic catalysts and site-differentiated ligands for preparation thereof
    Patent number: 11833495
    Abstract: Phosphine phosphonate and phenoxyphosphine ligands bearing polyethylene glycol (PEG) chains are used as described herein to produce heterobimetallic catalysts. The ligands can be metallated selectively with palladium or nickel and secondary metal ions to provide well-defined heterobimetallic compounds. These heterobimetallic complexes exhibit accelerated reaction rates and greater thermal stability in olefin polymerization compared to other catalysts.
    Type: Grant
    Filed: March 22, 2023
    Date of Patent: December 5, 2023
    Assignee: UNIVERSITY OF HOUSTON SYSTEM
    Inventors: Loi Hung Do, Zhongzheng Cai, Thi Tran, Dawei Xiao
