Key progresses of MOE key laboratory of macromolecular synthesis and functionalization in 2022

In 2022, The MOE Key Laboratory of Macromolecular Synthesis and Functionalization in Zhejiang University had achieved several important results. First, a series of well-defined dinuclear organoboron catalysts were developed to precisely control the enchainment of ether and carbonate segments during the copolymerization of CO2 and epoxides. Second, polyester had been synthesized through cationic copolymerization of cyclic anhydride. Third, ring-opening polymerization of carbon dioxide based valerolactone had been achieved, revealing the prospect of 3-ethylidene-6-vinyltetrahydro-2H-pyran-2-one (EVL) in utilizing CO2 and synthesizing functional polymers. Fourth, machine learning methods have been applied to biomaterial research, enabling high-throughput screening of functional biomaterial surfaces for implantable devices, and searching for potent antimicrobial peptides in whole combinatorial peptide libraries. Fifth, methods of characterization of biomacromolecule RNA transcription and manipulation of nucleoside modification were developed. Sixth, artificial enzymes-armed Bifidobacterium Longum probiotics were established to tune down gut inflammation. Seventh, three-dimensional (3D) printing technologies were used to engineer tough supramolecular hydrogels. Eighth, hydroplastic foaming graphene frameworks for acoustic and conductive polymer composites were provided for application. Ninth, aggregate photophysics about the nature of through-space interactions (TSIs) and manipulating their strength in small molecules with non-conjugated structure had been elucidated. Tenth, the forming mechanism of a newfound nested texture in poly(l-lactic acid) (PLLA) spherulitic films had been revealed. Finally, the isotropically dyeing mechanism of KDP single crystals grown from hydrogels have been explored. The related works are reviewed in this paper. This paper provides a brief review of the key progresses in 2022 of MOE Key Laboratory of Macromolecular Synthesis and Functionalization in Zhejiang University, China. [Display omitted]
