MindMap Gallery Classification of Photochemistry
In the classification of photochemistry, photoredox catalysis focuses on the design of catalysts for light-driven redox reactions and their application in synthetic chemistry, along with the study of reaction mechanisms. Photocycloadditions explore the types of reactions, conditions, and product structures. Additionally, primary photochemical processes, including light absorption, energy transfer, and photochemical reactions, are also crucial aspects of photochemistry research.
