In a second part, the role of photochemistry as multidisciplinary science will be highlighted. In particular it will be shown the importance of the processes initiated and/or controlled by light in multifaceted applications in different fields, encompassing optoelectronics, environment, biology and medicine.

Strategies of Organic Synhesis
Prof. G. Tomaselli

In view of the required better use of feedstocks and the change in feedstocks, the role of selective catalysis will become even more important. The goal of the course is to familiarize the class participants with the design of supramolecular catalytic systems, which are smaller and structurally simpler than enzymes, but differently from enzymes allow to estimate the relative importance of different factors contributing to catalysis. Enzymes remain a source of inspiration, but more convenient routes to catalytic system based on organometallic catalysts and containing supramolecular features are needed. Several new approaches avoid the use of elaborate syntheses.
