Ms. Asuka Jo (2nd-year Master’s student, Laboratory of Photoreactive Molecular Science) received the Poster Presentation Award at the International Conference on Chiroptical Science 2025 (ICCS-2025).
Summary
Ms. Asuka Jo received the Poster Presentation Award at the International Conference on Chiroptical Science 2025 (ICCS-2025), held from September 17 to 19, 2025, at Kyoto Institute, Library and Archives, Kyoto Prefecture University. ICCS-2025 is an international conference devoted to intensive discussions on molecular optical chirality, bringing together leading researchers from Japan, Italy, China, Hong Kong, Korea, Taiwan, the United States, France, and other countries. The poster presentations were evaluated based on the academic achievements and presentation skills of graduate students, and a total of 11 students received the award.
Presentation title

Research detail
Molecular chirality is closely related to the origin of life and to the operating principles of optical devices such as liquid crystals, and it has been extensively studied in the fields of organic chemistry, photophysical chemistry, and electronic engineering. In particular, binaphthyl derivatives, consisting of two directly connected planar naphthalene units, have long been the subject of research and practical applications. While previous studies have focused on the planar naphthalene-based derivatives, in this work we successfully synthesized, for the first time, binaphthyl derivatives composed of a curved corannulene skeleton. Their chirality and isomerization behavior are thoroughly investigated and compared with the results of quantum chemical calculations.
Comment
I am truly honored to receive the Poster Award at ICCS 2025. I am deeply grateful to Professor Tsuyoshi Kawai, Assistant Professor Mihoko Yamada, Mr. Ryuta Imai, and all the members of the Laboratory of Photonic and Reactive Molecular Science for their generous support throughout this research. Although I felt nervous about discussing in English at an international conference, I was grateful that many participants showed great interest in our work, which enabled me to reaffirm the significance of this research. Encouraged by this award, I am determined to further advance my research and continue striving for new achievements.
