Abstract

During his general lecture before the International Congress of Applied Chemistry in New York in 1912, Giacomo Ciamician, one of the pioneers of modern organic photochemistry, presented his spectacular vision on "The Photochemistry of the Future.

On the arid lands there will spring up industrial colonies without smoke and without smokestacks; forests of glass tubes will extend over the plains, and glass buildings will rise everywhere; inside of these will take place the photochemical processes that hitherto have been the guarded secret of the plants, but that will have been mastered by human industry which will know how to make them bear even more abundant fruit than nature, for nature is not in a hurry and mankind is."

During that time, photochemical experiments mostly took place on the roof tops of chemical institutes or in southern countries (Figure 1), and the reaction mixtures were exposed to direct sunlight over long periods of time— often several months. With the development of powerful artificial light-sources, photochemistry finally moved into the laboratories and became an important and successful research field. However, despite obvious advantages in terms of selectivity and sustainability, photochemical applications for the production of chemicals on large industrial scales remained rare and Ciamician's dream seemed unfulfilled.
