Photochemical reactions are versatile processes for inorganic and organic syntheses. Synthesis using light as reagent and producing complex molecules from simple starting materials is exemplary realized in natural photosynthesis. Mankind still struggles for an efficient molecular system that mimics the natural process. In order to harvest light energy and to transform it into chemical energy, photochemical reactions have to be studied and optimized for synthetic applications. In recent years, photocatalysis has regained momentum because it combines the well established concepts of metalcatalysis and organocatalysis with the ideas of photoinduced electron transfer. Altogether, photo redox catalysis will be one of the major topics in modern photochemistry of the next decades. Nonetheless, also traditional photochemical reactions such as photocycloadditions and -cyclizations,
photochemical rearrangements, photoreductions, photooxidations and -oxygenations, photoinduced group transfer reactions and applications of photoremovable protecting groups, photochromic systems or photodegradation processes have to be studied and develop in the future
in order to satisfy the needs for a more sustainable synthetic chemistry.
This special issue of Molecules welcomes previously unpublished manuscripts covering all aspects of photochemical reactions including their design, product assessment, methodology development and applications.
