        Professor Michiya Fujiki was invited to visit our college and give a lecture entitled “Controlled mirror symmetry breaking, restoration, inversion, and memory in polymers, molecules, and lanthanide complexes detected by CPL-and-CD spectroscopy” at the conference hall of the College of Chemistry and Materials Science on June 4, 2019.

        Professor Michiya Fujiki received the Ph.D. degree from Kyushu University, Fukuoka, Japan, in 1993. Since 1978, he worked for Nippon Telegraph and Telephone Cooperation (NTT). From 1978 to 1982, he studied low-loss optical plastic fibers, and from 1983 to 1987, he studied the preparation and thin film properties of semiconducting phthalocyanine derivatives. In 1987, he joined the Basic Research Laboratories of NTT. Since then, he was engaged in the study of synthesis and photophysical properties of optically active polysilanes and π-conjugating polymers. He moved to NAIST as a full Professor in May, 2002. His research interests include the design and functionality of hierarchical architecture using the 14 group element polymers and phthalocyanine supramolecular polymers, and possible answers to the fundamental question of the origin of homochirality on Earth. He has contributed as an author and/or coauthor of over > 300 original and review papers, book chapters and editor of two ACS books, and 150 patents with the h index of 56. Among his publications, 33 papers were highlighted as front/back covers of RSC and Wiley journals.

        Since the time of Pasteur-Le Bel-van’t Hoff-Fischer-Cotton-Marckwald, many researchers have been devoted to realize a controlled synthesis and an efficient detection of desired optically active substances under chemical and physical influences over 150 years. These topics have long been the central subject in organic chemistry, supramolecular chemistry, pharmaceutical chemistry, polymer chemistry, analytical chemistry, materials science, and molecular machines. In recent years, Professor Michiya Fujiki and coworkers proposed several non-conventional approaches of obtaining optically active substances based on ideas of photon confinement in an optical cavity, self-focusing ball-lens effects, far-from equilibrium system with open flows of external energy and chemicals, tunneling and non-tunneling of rotational freedom in a double-well potential of substances, the nature of massless circularly polarized light source as a function of wavelength (energy), and invisible inter-/intramolecular weak interactions. They showcased several outcomes of facile generation, restoration, inversion, long-term memory, and real-time detection of optically active substances from the corresponding optically inactive substances in a catalyst free and loss-less processes operating at ambient temperature in a few minutes.

        At the end of lecture, the faculty members and students had intensive discussion on the lecture content with Professor Michiya Fujiki. Professor Michiya Fujikicomprehensively answered the questions with his extensive scientific knowledge and research experience.
