Light and the New Chemistry

Expectation for Photo Technologies
  • Yoshikazu Ito


Sun light has been providing clean energy on the Earth since the mythical age. Almost all livings on the Earth have been benefiting from the solar energy through photochemical and biochemical processes in nature. So, photochemistry is fundamentally an eco-and human-friendly technology. However, it took us a long time to utilize the photochemical reaction practically. Table 1 shows the epoch-making discoveries at the dawn of photochemistry.
