Photochemistry (a term that broadly speaking includes photophysics) is abranchofmodernsciencethatdealswiththeinteractioflightwithmatter and lies at the crossroadsof chemistry, physics, and biology. However, before being a branch of modern science, photochemistry was (and still is today), an extremely important natural phemen. When God said: Let there be light , photochemistry began to operate, helping God to create the world as wewkwit.Itislikelythatphotochemistrywasthesparkfortheorigif life on Earth and played a fundamental role in the evolution of life. Through the photosynthetic process that takes place in green plants, photochemistry is responsible for the maintenance of all living organisms.

Photochemistry as a science is quite young; we only need to go back less than one century to ?nd its early pioneer . The concept of coordination compound is also relatively young; it was established in 1892, when Alfred Werner conceived his theory of metal complexes . Since then, the terms coordination compound and metal complex have been used as synyms, even if in the last 30 years, coordination chemistry has extended its scope to the binding ofall kinds of substrates [3, 4].
