The use of organocatalysts able to photocatalyze an organic reaction is a rapidly growing field. These photocatalyzed transformations are more environmentally sustainable with respect to the use of expensive/toxic metal-based (photo)catalysts.Based on the authors' extensive experience in photogenerated intermediates, this book presents an overview on photocatalyzed organic processes having a synthetic significance, where an organic molecule functions as the photocatalyst.After a brief introduction defining the nature and the characteristics of a photoorganocatalyst (POC), the chapters are organized according to the class of POC used, as detailed below.Each chapter begins with a summary of the photophysical characteristics of the POCs and is followed by selected examples of synthetic applications. The last two chapters are devoted to the adoption of photoorganocatalysis in polymerization and to flow photoorganocatalysis. These in-depth explanations and practical applications make this title an essential reading for any chemistry student interested in organic (sustainable) synthesis.

Providing critical analysis of the topics, this book is essential reading for anyone wanting to keep up to date with the literature on photochemistry and its applications."A certain amount of energy destroys the same amount of CO2 according to the whether it is administered continuously or intermittently. In order to rationalize this result there are two possibilities, either the destruction of CO2 further occurred in the dark periods, which would lead to the same form of energy storing form, or in the illuminated period the reaction goes at twice the rate."O. Warburg, Biochem. Z., 1919, 100, 230–270.

This issue of Photochemical & Photobiological Sciences is dedicated to Prof. Angelo Albini on the occasion of his 75th birthday. It includes original articles and reviews from colleagues, former students, but especially friends, from the (photo)chemical community. It is a pleasure to dedicate this issue to Angelo because of the great contributions he gave to the study of light-driven reactions and to the photogeneration of reactive intermediates to be used in synthesis and to the understanding of mechanisms involved in photoinduced processes. The beginning of his career has been devoted to the photochemistry of heterocycles (e.g. phenazines), then his innate curiosity and enthusiasm in facing new challenges pushed himself towards the study of different topics, including photoinduced electron (and hydrogen-atom) transfer, nitrenes and singlet oxygen chemistry, the photodegradation of drugs and the photogeneration of triplet phenyl cations. This issue is made by more than 35 papers virtually covering all photochemical topics, including photosensitization, photoinduced electron transfer, photocatalysis, photobiology, photodynamics, chemiluminescence, light-driven bond cleavage, photocycloaddition, photocaged molecules, helical compounds and reactive intermediates in environments with restricted diffusion (e.g. micelles, organic capsules). As an active part of the photochemistry community, we are indebted to the huge work Angelo developed during his career and we thank all the contributors for being part of this exciting project. Finally, we would like to thank Angelo, a special friend and a mentor for us, remembering that his scientific heritage is still alive in the PhotoGreen Lab at the University of Pavia. Grazie, Angelo!
