The basic principles of Photophysics and photochemistry applied to photocatalisys

• Unimolecular and bimolecular excited state decay processes
• Dyad photosensitizer-catalist in pohotocatalysis
• Photoinduced Electron transfer: Markus theory and quantum approach
• Energy transfer: Förster and Dexter mechanism
• All-in-one example: [Ru(bpy)₃]²⁺ in electron-trasfer and energy transfer photocatalysis
• How to investigate photocatalytic processes: experimental tecniques (absorption and emission spectroscopies, photochemical kinetic measurement within Stern-Volmer equation) and computational approches (Time-dependent DFT)

Photophysics:

Objective of the program: The mini-course of photochemistry is an introduction to a selection of general, organic, inorganic, biological, solid state and theoretical photochemical themes with the aim of providing to phd students knowledge in basic principles and application of photochemistry.

Final evaluation: Individual oral interview by which the level of knowledge acquired is verified in terms of autonomy of analysis and judgment and in terms of ability to critically evaluate the contents developed during the teaching
