Angew. Chem. int.ed. Publishes ECUST Research in Reactive Diffusion-mediated Dynamic Supramolecular Gels  

Recently, the research team of Professor Guo Xuhong, ECUST proposed a new strategy to control dynamic supramolecular self-assembly through reaction diffusion. Based on a kind of polyacrylic acid/amorphous calcium carbonate (PAA/ACC) supramolecular gel system, the dynamic growth of structured supramolecular hydrogels was successfully realized. The research article was published in Angew.chem.int.ed. with the title “Dynamic growth of macroscopically structured supramolecular hydrogels through orchestrated reaction-diffusion”.

The authors successfully created a macro-structured supramolecular hydrogel with dynamic characteristics by controlling the transfer and dynamic assembly of substances in space by reaction diffusion, which is a new attempt to develop life-like functional materials and is expected to promote the construction of new soft material and its unique application in biomedicine, intelligent sensing and other fields. Due to the team’s series of progress in the field of chemical reaction-mediated dynamic supramolecular hydrogels, the team was recently invited by Chem. Commun. to write a feature article entitled “Dynamic supramolecular hydrogels mediated by chemical reactions” (Chem. Commun., 2023, 59, 14236-14248) . The research work was conducted by Dr. Wang Hucheng under the guidance of researcher Yiming Wang and has received guidance from Professor Guo Xuhong. The calculation part of the reaction-diffusion model was completed in cooperation with Dr. Fu Xiaoming and Professor Cao Zhixing. The research has been funded by the National Natural Science Foundation of China, Shanghai Chenguang Project and Shanghai Natural Science Foundation.
