“…In addition, cyclic topology can also be fixed by eliminating the vinyl double bond of furan/maleimide adduct by the photoinduced radical thiol‐ene reaction. [ 46 ] In practice, firstly, a cyclic poly (methyl methacrylate) (PMMA) chain was synthesized, wherein the furan/maleimide dynamic covalent bond was embedded. The transformations from cyclic PMMA to linear multiblock polymer and linear homopolymer were then realized by manipulating the reaction temperature and concentration of the polymer.…”

Herein is presented a compilation of the main characteristics of maleimide chemistry in developing the precisely controlled polymers, including the design of sequence‐controlled polymers, topological polymers, and polymeric single‐chain nanoparticles. The synthetic methods, relied on the versatilities of the maleimide moieties as a latent monomer which leads to an efficient alternative in various innovative applications, especially in self‐healing material, self‐reporting materials for real‐time monitoring, and also in data storage and anticounterfeiting technologies. The core of the content in this review is focused on the up‐to‐data advances and publications on the major of maleimide chemistry in our research group. What is the most favorite and original chemistry developed in your research group? Maleimide chemistry in precision polymer synthesis. How do you get into this specific field? Could you please share some experiences with our readers? When I was a junior high school student, the chemistry attracted me very much. Chemistry is an extraordinary magic, which virtually generates molecules, basic units and everything on earth. I selected the polymer chemistry area when I pursuit my MSc and PhD in Soochow University. The polymer chemistry is the basic and originality of polymer science, which has created tremendous useful materials and greatly benefited humanity in the past century. Engaging in chemistry research is tedious and hard most of the time, but I like the joy and accomplishment at the moment when the experiment succeeds. It's like tea tasting, the kind of fleeting back sweetness makes me yearn and intoxicated. How do you supervise your students? I always encourage students to believe themselves, however don't always believe what others have said. The students should have their own judgments based on broad literature survey, comprehensive learning and deep thinking. The students should not take the publications but the improvements of research capability as the only target when pursuing the academic degree. What is the most important personality for scientific research? Be joyful, enthusiastic, persistent and careful. How do you keep balance between research and family? I like cooking for my family. Cooking is similar with chemical experiments. I think that cooking is a good balance between research and family.

“…Starting with this paper, heat-healable networks with maleimide or furan [26][27][28][29] have been reported, contributing to the longevity of polymeric materials. The reversibility of DA reactions also allowed for the control of topological changing 30 and sequencing 31 of polymers. Therefore, the furan has been proven to be an effective structure for polymer reactions.…”

Biobased furan polymers (BFPs) derived from 5‐hydroxymethylfurfural (HMF) are eco‐friendly polymers obtained from inedible biomass resources. Modification of such polymers is expected to expand their practical uses. BFPs have furan moieties that can react as dienophiles with maleimide, facilitating well‐designed polymer reactions. Herein, we report the preparation of various maleimides using p‐maleimidophenylisocyanate (PMPI), which has a highly reactive isocyanate group and a maleimide group, to modify BFP through the Diels–Alder reaction of the maleimide group. Two reactive sites in PMPI exhibit orthogonal reactivity, enabling us to achieve tailor‐made modification agents. The Tg values and rheological properties of modified polymers can be tuned according to the structure of maleimide and their reaction conversion, which demonstrates the practical usability of BFP derived from furfural. The strategy proposed herein can be applied to obtain biobased materials with desirable functions and physical properties.

“…[ 12–14 ] In addition to uncovering such unique properties of cyclic polymers, an actively pursued topic in this area is to create dynamic properties. [ 15–19 ] Regarding this, a solventless dramatic change in the fluidity of poly(dimethyl siloxane)s (PDMSs) based on cyclic–linear topological transformation has been realized, in which reversible photochemistry of hexaarylbiimidazole (HABI) has been utilized for switching cyclic and linear topologies. [ 20 ] HABI is known as a photo‐, [ 21 ] mechano‐, [ 22 ] and thermoresponsive [ 23,24 ] molecule due to the presence of a relatively weak covalent bond between the two imidazole groups.…”

Perfluoropolyether (PFPE) is an industrially important fluoropolymer and has great industrial importance due to its flexible, noncombustible, and chemically robust properties. However, exploration and application of chemically modified homogeneous PFPEs are hampered by their immiscibility against nonfluorine‐containing molecules. Here, the synthesis is reported of cyclic PFPE with hexaarylbiimidazoles (HABIs) in chains from linear PFPE having 2,4,5‐triphenylimidazole (lophine) end groups. While phase separation between the end groups and main chains took place for linear PFPE, HABIs and main chains in cyclic PFPE are miscible to form transparent glass films. The design of cyclic PFPE also enables cyclic to linear topological transformation based on conversion of HABIs into lophines upon mild heating in the glass film state. Sequential linear‐to‐cyclic and cyclic‐to‐linear topological transformations enable fabrication of thermostabilized transparent films derived from PFPE.
