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.

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!

Explore the potential of biomass-based chemicals with this comprehensive new reference from leading voices in the fieldWith the depletion of fossil raw materials a readily ascertainable inevitability, the exploitation of biomass-based renewable derivatives becomes ever more practical and realistic. In Biomass Valorization: Sustainable Methods for the Production of Chemicals, accomplished researchers and authors Davide Ravelli and Chiara Samori deliver a thorough compilation of state-of-the-art techniques and most advanced strategies used to convert biomass into useful building blocks and commodity chemicals.Each chapter in this collection of insightful papers begins by detailing the core components of the described technology, along with a fulsome description of its advantages and limitations, before moving on to a discussion of recent advancements in the field. The discussions are grouped by the processed biomass, such as terrestrial biomass, aquatic biomass, and biomass-deriving waste.Readers will also benefit from the inclusion of: A thorough introduction to the role of biomass in the production of chemicalsAn exploration of biomass processing via acid, base and metal catalysis, as well as biocatalysisA practical discussion of biomass processing via pyrolysis and thermochemical-biological hybrid processesA concise treatment of biomass processing assisted by ultrasound and via electrochemical, photochemical and mechanochemical meansPerfect for chemical engineers, catalytic chemists, biotechnologists, and polymer chemists, Biomass Valorization: Sustainable Methods for the Production of Chemicals will also earn a place in the libraries of environmental chemists and professionals working with organometallics and natural products chemists.
