Collaborative research with Tohoku University has been published in Polymer (IF=4.6). Topological interactions between cyclic and linear polymers have attracted significant attention to exploring the properties of soft materials. In this study, a blend system composed of a cross-linked polymer and a small amount of large-sized multicyclic polymers was prepared to achieve a reinforcing effect via rotaxane or catenane formation. this network polymer can be toughened by tuning the topological variables of the multicyclic chains (size and number of cyclic units) and the cross-link density of the network. This article suggests that a topological design can be useful for fabricating tough cyclic chain-mixed materials.

Weeranuch (Postdoctoral researcher) has published an article to Carbohydrate Polymers (IF=11.2). Isomaltomegalosaccharide is a "chimeric" saccharide where α-(1→4)-segment at the reducing end interacts with the lipophilic compounds to form a complex and the hydrophilic α-(1→6)-main chain solubilizes the complex. In this article, we newly generated the long α-(1→4)-segment at the nonreducing end of α-(1→6)-main chain by enzymatic methods. The products displayed aqueous solubilization of drugs, flavonoids, and curcumin while the aggregation level was lesser when compared with that of similar chain amylose. SAXS measurement confirmed the rigid and flexible conformation in solution. In our research, enzyme-generated functional biomaterials were developed to maximize the hydrophobic binding efficacy toward water-insoluble bioactive compounds.

Ph.D. Xia (former visiting researcher), Gao(D1) and Suzuki (D1) have published an article to Journal of the American Chemical Society(JACS). We reported self-switchable alternating copolymerization from a mixture of two different cyclic anhydrides, epoxides, and oxetanes, where a simple alkali metal carboxylate catalyst switches between ring-opening alternating copolymerization (ROCOP) of cyclic anhydrides/epoxides and ROCOP of cyclic anhydrides/oxetanes, resulting in the formation of a perfect block tetrapolymer.

Suzuki (D1) have published an article to Polymer Chemistry (IF=5.364). We have developed a new synthetic method for hyperbranched polyesters (HBPE) by ring-opening alternating copolymerization of epoxides and trimellitic anhydride, using cesium pivalinate as a catalyst. By appropriately selecting anhydrides, epoxides, and alcohol initiators, various HBPEs with different backbone structures can be obtained. Due to its versatility and simplicity, it has the potential to be used in a wide range of applications such as additives and biomedical applications.
