Key progresses of MOE key laboratory of macromolecular synthesis and functionalization in 2021

In 2021, The MOE Key Laboratory of Macromolecular Synthesis and Functionalization in Zhejiang University had achieved several important results. First, a series of versatile organoboron catalysts were synthesized for ring-opening (co)polymerizations. Second, a catalyst-free polycondensation mechanism was proposed for the production of polyesters with high molecular weights. Third, a co-assembly method that can fabricate films and coatings with controllable structures and properties on various substrates was demonstrated, providing a platform for the construction of novel surface coatings. Forth, facile methods for producing high-productivity poly(propylene carbonate) and semicrystalline polyester have been discovered. And linear non-conjugated polyesters exhibiting yellow-green clusteroluminescence were developed for the first time. Fifth, a supramolecular prodrug nano-assembly strategy has been developed for reactive nitrogen species potentiated chemotherapy. Sixth, a series of tough and stiff supramolecular hydrogels with shape memory properties have been used for information encryption. Seventh, reversible fusion and fission of wet-spun graphene oxide fibers has been successfully achieved. Eighth, three non-conjugated polypeptides were synthesized and the mechanism of clusteroluminescence was studied. Ninth, a series of conducting covalent organic frameworks with high electrical conductivity and carrier mobility have been used as high-performance chemiresistor, electrocatalyst, and organic field-effect transistor. Tenth, the exploration of non-fused electron acceptors, and their photostable mechanism are exemplified for developing high-performance, low-cost and eco-friendly polymer solar cells. Finally, gel-grown long-range ordering bulk-heterojunctions has achieved improved X-ray detector performance.
