At 15:30 on December 15, 2023, Professor Shi Feng from Beijing University of Chemical Technology was invited by Professor Huang Hui to give a lecture on "Macroscopic supramolecular Assembly and its Application" in the University of Chinese Academy of Sciences. The lecture was held in Room 305 on the first floor of the teaching Hall.

      Macroscopic supramolecular assembly refers to the process of constructing supramolecular materials by introducing supramolecular recognition groups through surface chemical modification on the construction primitive surface of more than 10 microns, and then assembling supramolecular materials by interface. It is a new research direction of supramolecular chemistry and provides a new idea for the preparation of bulk phase supramolecular materials.

      Professor Shi Feng first introduced the research of macroscopic supramolecular assembly, which can develop new functional materials by drawing on natural supramolecular materials. Moreover, the research of macroscopic supramolecular assembly can provide an ideal model system to explain the interfacial interaction widely existing in the field of materials science, and help to understand the relevant interfacial mechanism of action. Then, focusing on the problem of how to achieve efficient and accurate macroscopic supramolecular assembly, the design principle of high compliant surface is introduced from the perspective of the influence of interface deformation ability on assembly behavior. In the macroscopic supramolecular assembly, the collision and assembly of building elements depend on strong external forces such as vibration and rotation, resulting in poor matching degree and low order degree of the final assembly. Therefore, the team developed two strategies. For the system where the dynamic process of the imprecise structure is dominant, the difference in thermodynamic stability between the imprecise structure and the precise structure was utilized to develop a self-correcting strategy. Obtain accurate assemblies; For the system which can control the assembly dynamics and realize the precise structural dynamics process, the assembly of the system in the near thermodynamic equilibrium state is realized by constructing the spontaneous motion of the primitive, and the ordered structure is obtained directly. Finally, the three-dimensional ordered structure of heterogeneous materials is constructed by macroscopic supramolecular assembly, which solves the problem of efficient composite of heterogeneous materials in three-dimensional space, and expands the application range of supramolecular assembly. Professor Shi Feng conducted exchanges and discussions with the on-site teachers and students, and got a warm response from the on-site teachers and students.
