42Functional Polymer ScienceThe beginning of a New Polymer Synthesis: Materials by Molecular and Reaction Design Department of Chemistry and MaterialsFibers, plastics, rubbers… common materials are composed of macromolecules (polymers) built up from hundreds and thousands of small molecules. Our research focuses on creating new polymer materials by designing functional molecules and their reactions. For example, we aim the development of a facile method to synthesize a polymer from a higher fatty acid made from plants materials in order to create a new rubber from biomass. Depending on how we design the molecules to be used in the synthesis, we can create new materials that we could not be previously imagined. We are busy working hard making experiments every day. Yasuhiro KohsakaAssistant ProfessorDr. Kohsaka received his Ph. D. in Engineering from The Tokyo Institute of Technology. He worked as a JSPS Research Fellowship for Young Scientists (DC-1) and then as an assistant professor in Osaka University, before starting his current position at Shinshu University in 2015. In general, polymeric materials is a product of the petroleum industry. However, we also design polymers from natural products, aiming to develop a sustainable system by developing new synthetic technologies. Synthetic chemistry is very interesting, as it can be used to create many materials, such as the advanced materials used in medicine and solar cells, and everyday products made from bers and rubber. Outlook for researchYou can learn the logic that is needed in science, the English language, the way to make presentations, and the knowledge that future researches need. As this laboratory was only established in 2015, no students have graduated yet. However, this type of knowledge is indispensable in our society. Outlook for students after graduationFig. 1. Synthetic research on uorescent polymers. Polymers composed of a single monomer and those of two dierent monomers in alternating sequence showed dierent uorescent emission colors. Fig. 2. A polymer prepared from a β-amino acid derivative was a solution under acidic conditions and a low temperature, but become insoluble at higher temperatures.
