Kenntnisse |
| (*)More specifically, upon completion of the course, they will be able to
- understand the nature of light (k2, k3, k4).
- understand basic terms of photophysics and photochemistry (k2, k3, k4).
- understand and explain basic instrumentation relevant in photophysics and photochemistry (k2, k3, k4).
- apply basic concepts of photophysics and photochemistry (k3, k4, k5).
- interpret simple electronic spectra and assign the nature of exited states of molecules with a special focus on coordination compounds (k4, k5, k6).

(*)Underlying concepts and details of
- the nature of light and basic terms (electromagnetic spectrum; Grotthuss-Draper, Photoequivalence, Bunsen-Roscoe, Beer-Lambert law; black body, types of luminescence, photoelectric effect).
- the instrumentation used in photochemistry: light sources, monochromators, lasers, filters, examples of simple photochemical set-ups.
- basic terms and practical aspects of UV-vis-spectroscopy: HOMO-LUMO diagrams, solvato-, rigido- and thermochromism, isosbestic points, stopped-flow technique, solvents used for spectroscopy at ambient and cryoscopic temperatures.
- symmetry and spin selection rules; spin orbit coupling and heavy atom effect.
- spin selection rule and reactivity of singlet oxygen.
- band shapes in electronic spectra: Franck-Condon principle and Stokes shift.
- the fate of excited states: luminescence, photoreaction or non-radiative decay; quantum yields
- the Jablonski diagram: internal conversion, intersystem crossing, fluorescence, phosphorescence, vibrational relaxation; Kasha’s and El-Sayed rule, energy gap law, multiphoton processes.
- the interpretation of absorption and emission spectra on the basis of exemplary spectra of organic and coordination compounds including basic terms and characteristics of electronic transitions and excited states: -*, n-*-transitions; intraligand, metal centered, metal-to-ligand charge transfer, ligand-to-metal charge transfer, etc. excited states; thermally activated delayed fluorescence; excimers and exciplexes.
- photophysics and photochemistry of ruthenium(II) diimine complexes.
- emission life-time measurements and determination of emission quantum yields (e.g. chemical actinometry and integrating sphere).
