The Si-O-Si framework of the Si-O-Si framework bridged multi-nuclear boron catalyst can be a linear structure of Si-O-Si, a ring structure of Si-O-Si, or a cage structure of Si-O-Si. The feasibility of multiple types of topological structures provides controllability for the synthesis of multi-nuclear boron. The multiple Lewis acid centers of this type of system can better activate monomers and stabilize active species, reflecting the synergistic effect of multiple boron centers. The multi-nuclear boron catalyst of the present invention is mainly used in ring-opening polymerization and copolymerization to prepare diverse low-carbon polymers, such as polyethers, polyesters, polycarbonates, etc.
