2026.03.18，Tibor Kudernac from University of Groningen visited the Department of Macromolecular Science at Fudan University and delivered a report titled Life-like supramolecular mechanics. The report introduced that they seek to close the gap between molecular motion and macroscopic function by establishing supramolecular (de-)polymerization as a general engine for force generation. Inspired by cytoskeletal dynamics, they design artificial assemblies that transform molecular switching into collective mechanical action Light-responsive supramolecular tubes, incorporating molecular photoswitches, undergo controlled growth and collapse in water. Because molecular isomerization is faster than structural relaxation, disassembly proceeds through cooperative strain build-up, producing directional forces capable of moving micron-scale objects. Building on this concept, we further developed a synthetic depolymerization motor in which regulated disassembly of rigid microcrystalline fibers produces anisotropic etching and directional pulling forces.
