Information (Updated: Oct 14, 2021)

Pacifichem 2021 announced on Oct.8 that they will take place only virtually. However, our symposium will still take place as a hybrid one.
It will be held at Outrigger Kona Resort and Spa on December 12(Sun)-15(Wed), 2021 as the pre-symposium of the Pacifichem 2021.
We are looking forward to seeing you in Hawaii.


On behalf of organizing committee, we warmly welcome you to the "4th International Symposium on
Photofunctinal Chemistry of Complex Systems (ISPCCS2021)" which will be held in Kona, Hawaii on December 12(Sun)-15(Wed), 2021.

The symposium will focus on the photochemical and/or photophysical functions of the complex systems. The complex systems are beyond simple and small organic or inorganic compounds, and they include metal complexes, supramolecular systems, macromolecules, and biological systems. Model systems for natural photosynthetic systems are also one of the important topics. Specific topics to be covered include novel molecules with exciting photochemical or photophysical properties like luminescence, photochemical drugs and solar energy conversion, unique synthetic and theoretical strategies for such molecules, innovative molecules and/or complex systems applicable to the practical use. The symposium will highlight many of the recent developments in broad area of photochemistry, photophysics, and photobiology, with a particular emphasis on how the molecules with photochemical/photophysical functions are designed and how the molecules are applied to practical use. We wish that you will discuss with the other participants and make friends, leading this symposium fruitful. And we hope that this scientific field will become much more active after the symposium.

We look forward to welcoming you in Kona.
