Dear ICPOC-25 Participants,

I would like to take this opportunity to thank you for taking time out of your busy schedule to attend ICPOC-25 in Hiroshima. Thanks to your warm cooperation, we were able to complete the conference (our mission!) without any major problems. I would like to express my deepest gratitude for the opportunity to host this conference. Myself and the members of my laboratory have grown not only as chemists but also as human beings through this conference. Thank you very much.

As I mentioned in my closing remarks, researchers in physical organic chemistry are able to design new molecules and reactions by themselves, synthesize and perform reactions by themselves, and furthermore, investigate physical properties and analyze reactions by themselves. And finally, they can return the developed substances and reactions to society. Physical organic chemistry allows us to conduct chemical research from beginning to end. If we do basic research, we will be able to propose new ideas. The active chemistry that is flourishing today is important, but it is physical organic chemistry that can develop new chemistry that will flourish in the next era. Let’s enjoy creating new chemistry!

See you in Beijing in August in 2024 at ICPOC-26!

Welcome message

Dear colleagues,

I am very happy to announce to hold the 25th IUPAC International Conference on Physical Organic Chemistry (ICPOC 25) in Hiroshima, Japan, from 10th to 15th July 2022.

Since the first meeting in 1972, the ICPOC meetings have been the leading international gatherings on Physical Organic Chemistry.

Traditionally, Physical Organic Chemistry relates molecular structure to chemical behavior, by means of the study of structure, reactivity, mechanism and equilibrium in organic systems, aiming at the quantitative, molecular level understanding of their properties. Nowadays, Physical Organic Chemistry encompasses a much wider range of contexts, extending into materials science, biology and systems chemistry. The ICPOC 25th will focus on discussing (1) Organic Reactivity and Reactive Intermediates Chemistry, (2) Theoretical and Computational Organic Chemistry, (3) π-Conjugated Molecular and Materials Chemistry, (4) Organic Photochemistry, (5) Supramolecular Chemistry, (6) Organic Main Group Chemistry, and their related chemistry.

This comprehensive and multidisciplinary approach plays a pivotal role in the development of chemical sciences, expanding their boundaries, and reflects on the vibrant and enlightening scientific discussions usually held in ICPOC meetings.

Together with an outstanding scientific program, you will feel the colors, flavors, tastes, history and traditions of Hiroshima area. I strongly encourage young chemists to come to Hiroshima and enjoy the ICPOC meeting.

I am very much looking forward to seeing you in Hiroshima, Japan, in 2022.

Manabu Abe
