PACIFICHEM 2025

Dear Colleagues:

It is our great pleasure to announce the Symposium “Nitroxide Radicals: Synthesis and Functional Bio-/Nanomaterials” (#MAT011) organized as a part of Pacifichem 2025, December 15-20, 2025, Honolulu, Hawaii, USA. The official full name of Pacifichem 2025 is the 2025 International Chemical Congress of Pacific Basin Societies. This will be the ninth meeting of this prestigious Congress, which has been held approximately every five years since its founding in 1984. The Congress is organized as a series of independently organized Symposia covering an exceptionally wide range of chemical disciplines.

The “Nitroxide Radicals: Synthesis and Functional Bio-/Nanomaterials” Symposium builds on the success of the three preceding EPR-themed symposia at the PACIFICHEM 2010, 2015, and 2021 focused primarily on nitroxide free radicals. The 2025 Symposium is expanding to reflect further progress in new redox and antioxidant chemistry of nitroxides and other free radicals. We are also planning to include the topics of chemistry and characterization of functional materials with spin centers that exploit the chemical and quantum spin properties provided by these unique chemical architectures. Thus, the 2025 symposium will focus on:

1) Synthesis of organic radicals and materials engineering of spin centers with designed functionality;

2) Redox-active and reactive nitroxides – from biological probes to all-organic batteries;

3) Chemistry and physical properties of supramolecular spin assemblies;

4) Spin centers as building blocks for spintronics and quantum information processing.

The Symposium will follow the common theme of spin centers and free radicals in chemical systems and materials of increased complexity: from organic synthesis of small molecules to engineered quantum defects in crystals, to supramolecular assemblies, nanoclusters, and low-dimensional bio-/nanomaterials. The transdisciplinary nature of the Symposium brings together organic synthetic, supramolecular and materials chemists as well as experts in EPR spectroscopy, quantum information, and materials science. The Symposium will provide unique means to disseminate recent research results in free radical chemistry and applications among the disciplines and diverse Pacific Rim scientific communities, thereby fostering new interdisciplinary collaborations, industrial development, and inspiring discoveries that are expected to rapidly transform the field.

Participants of the “Free Radical” Symposium are also encouraged to attend other symposia and events organized within PACIFICHEM 2025 and covered by the Congress registration.  For more information, please see https://pacifichem.org/.  Note that the oral sessions of our Symposium are scheduled on Dec. 15 (Mon) and Dec.16 (Tue) from 8 am to 5 pm on both days. The exact location of the oral sessions and the date of the poster session have not been determined yet.

Please note the important dates:
