The discovery of quasicrystals that have non-crystallographic rotational symmetry is one of great milestones in physics and material sciences in the late 20th-century. However, quasicrystalline structures had not been observed in any polymeric systems. In this research project the author showed evidence of a "polymeric quasicrystal" tiling for the first time, and studied polymeric quasicrystals theoretically. The present results elucidated the universal nature of quasicrystalline order from metals (hard matter) to polymers (soft matter). The work attracted much attention from both physics and chemistry fields.
