CY6124 : Organic Photochemistry: Principles and Applications

Course objectives: Learn the fundamental ideas of photochemical excitation/de-excitation events, and the molecular events that can intervene at different levels and their applications.

Learning Outcomes: At the end of the course, the learners should be able to:

Predict the course of an organic photochemical reaction and identify the product with the type of functional group present on the molecule

Apply photochemistry concepts, plan and program molecules for photochemical application of specific interest

Appreciate the photochemical phenomena by light and be able to design and practically carry out simple photochemical reactions

Course Contents:

Fundamentals – Energy and electronic spin states – spectroscopic transitions – photophysical processes, fluorescence and phosphorescence – energy transfer and electron transfer, and properties of excited states – reaction mechanisms Experimental Techniques – Photochemistry of olefins, carbonyl compounds, aromatic molecules – nitrogen containing compounds (nitro, azo, and diazo compounds) – molecular oxygen – photofragmentation and elimination reactions – photolytic deprotection and activation of functional groups – electron transfer reactions – applications to organic synthesis

Supramolecular photochemistry – Photochemistry in organized and constrained media – Organic photoresponsive materials

Some applications in biochemistry, biology, medicine and technology.
