The 76th Yamada Conference

The 9th International Conference on Nitroxide Radicals (SPIN-2023)

*Note  Please check updated Info & Program. (updated on September 16th)

               Information and Presentation pages are also updated.

Yokohama, Japan, September 24-28, 2023

 Chemistry of nitroxide has undergone rapid growth due to combined progress in several areas including the design and synthesis of nitroxide radicals with targeted physical and chemical properties, the development of novel materials and supramolecules that take advantage of nitroxide functionality and parallel progress in new spectroscopic methods. The conference will cover

1) Synthesis of functional nitroxide radicals;

2) Chemistry and physical properties of nitroxide radicals;

3) EPR studies using nitroxide radicals (spin labeling, spin probing,  DNP, MRI, etc.);

4) Application of nitroxide radicals in medicine and living systems;

5) Application to materials (redox systems, molecule-based magnet, etc.)

This conference was initially scheduled in 2020, but was postponed due to the COVID-19 pandemic.
