COURSE DESCRIPTION: This course deals with selected aspects and tools of modern photochemistry in solution and solid state. Combination of lectures
with carefully selected practical exercises should give students good basic understanding of photochemical processes, their mechanisms and usefulness of photomaterials.
PART I: Inorganic photochemistry (Prof. G. Stochel, Dr. Wojciech Macyk, Dr. Konrad Szaciłowski)Fundamental photochemical laws. Techniques used in studies
on mechanisms of photochemical reactions (continuous and flash photolysis, quantum yield measurements, photoelectrochemistry, spectroelectrochemistry). Photochemical
reactions of coordination compounds. Mechanisms of selected photochemical processes (photoinduced charge and energy transfer, photosensitization, photocatalysis and
others) in biology, medicine, environmental protection, industry. Semiconductor photocatalysis.
PART II: Photoactive polymers and antenna systems (Prof. M. Nowakowska, Dr. Mariusz Kępczyński, Dr. Krzysztof Szczubiałka) The photochemical reactivity of
microheterogeneous systems. Applications as light harvesting and antenna systems, photocatalytic centers useful in environmental protection and medicine,
photomaterials, etc. Photoreactions in synthetic polymers and biopolymers. Photopolymerization: photoinitiators and mechanism. Application of photopolymerization.
Cross-linking processes initiated by light. Photoactive polymers, negative and positive photoresists. Photolithography.
OBJECTIVE OF THE COURSE:
The aims of this unit are:
- To demonstrate the application of spectroscopic and electrochemical methods in mechanistic studies of photochemical reactions
- To make students familiar with a broad variety of photochemical systems and their applications
INTENDED LEARNING OUTCOMES:
After completing this unit students should be able to propose a method suitable for mechanistic studies
of a particular homogeneous or heterogeneous photochemical system as well as suggest the type of photomaterial for a specific application
