Helical Polymer Laboratory 

Our laboratory focuses on developing functional polymers with controllable helical conformations and tunable handedness. We specialize in helical polymers and chiral amplification, investigating how molecular design allow polymers to switch helicity in response to stimuli such as light, heat, solvents, metal ions, and chiral additives. These transitions give rise to distinctive chiroptical properties, including circular dichroism (CD) and circularly polarized luminescence (CPL). A key research direction is the helicity memory effect, where polymers retain induced helicity even after removing the chiral source. Such materials show strong potential in chiral sensing, enantioseparation, optoelectronics, and switchable smart films. We also construct hierarchical supramolecular architectures—such as helical nanofibers and superhelices—using hydrogen bonding, metal coordination, and dynamic covalent interactions. Integrating polymer synthesis, spectroscopy, and materials engineering, our goal is to create next-generation responsive, programmable, and chiroptically active helical polymer systems.
