The Advanced Polymer Science Laboratory is devoted to breaking common sense and knowledge, textbooks, established theory, and historical knowledge, aiming to realize unique chiroptical photophysics of polymeric materials. The issues we focus on are as follows:

 

Generation, amplification, inversion and transcription of helix structures by chemical and physical origin

We aim to cultivate capable researchers and engineers who will work in the area of polymer-related science and engineering through ground-breaking outcomes in relation to the design, synthesis, analysis, and function of polymers. We focus on educating students to independently think about new concepts and to propose new ideas through daily reciprocal interaction, as well as in seminars and meetings hosted by related academic communities.

1. Mirror symmetry breaking at polyatomic systems and elucidating the origin of life on Earth

2. Detecting ultraweak molecular interactions

3. CPL-functioned polymeric materials using catalyst-free zero-step synthesis

4. Liquid-phase physisorption of π-conjugated polymers at inorganic/polymer interfaces
