Macromolecules are giant molecules composed of tens of thousands of connected atoms, which possess unique characteristics that cannot be found in small molecules. They are used in a wide variety of fields, from daily life to cutting-edge technologies. Our laboratory researchs highly functional and high-performance macromolecules composed only of carbon and hydrogen, which have excellent environmental adaptability. We put special effort into magical powders called transition metal catalysts, incorporating them into the synthesis and property analysis of soft materials such as gels and liquid crystals.
