Photoreaction Control
and
Photofunctional Materials

This page is organized by COE on PCPM project.
With the 21st-century close at hand, we are now confronted with serious global problems concerning energy and the environment. The ultimate solutions for these problems will be provided by the development of innovative technologies such as artificial photosysthesis and highly selective chemical reactions, both contributing to the effective utilization of solar energy and synthesis of materials with no unwanted side products. The control of photoreactions will be a key factor in these developments. Moreover, the "photon" plays and important role in the multimedia era, where various photofunctional materials constitute essential elements in the high-speed processing and transfer of huge amount of information.
