Bachelor's lectures and courses
The lecture considers general properties and their trends, modifications, preparation, uses, and chemistry of the nonmetals and metals in elemental form. In addition, the preparation and properties of hydrogen compounds, oxides, oxoacids, and halides of the nonmetals are covered using simple, selected examples, incorporating thermodynamic and kinetic concepts. Conceptually, structure of matter, molecular orbitals, MO schemes of diatomic molecules (H2, F2, O2, N2), structures (VSEPR method), bonding ratios as well as redox processes and electrochemistry, crystal structures, semiconductors, material properties, as well as natural cycles and environmental aspects (ex. Ozone, CO2, NOx, elements) will be covered, as well as the chemistry of transition metals in aqueous solution, the fundamentals of complex chemistry (formation and stability of metal complexes, introduction to ligand field theory, complex geometries and isomerism, ligand types). All course contents are underpinned by demonstration experiments.

Synthesis of organic and inorganic compounds according to different mechanisms and using different working techniques as well as characterization of the compounds by different methods. The compounds are organized in thematic complexes, whereby the student is assigned individual examples from a group of methodologically similar syntheses.
The program includes the syntheses of organic compounds by nucleophilic or radical substitution, addition or elimination, reduction or oxidation, aromatic substitution, condensation, diazotization and a transformation of/to a carbonyl or carboxyl derivative. A compound thereof is to be prepared on a semi-microscale. Furthermore, a mixture of substances is to be separated and the pure substances contained therein identified, a natural substance is to be isolated and a reaction with an organometallic reagent is to be carried out. In the field of inorganic synthesis selected substance classes of inorganic and metal-organic chemistry are synthesized: simple metal complexes, molecular inorganic compounds of the main group elements, the use of Li- or Mg-organyls in inorganic chemistry and metal-organic compounds of transition metals (metal carbonyls, sandwich complexes etc.).
All products are characterized by suitable spectroscopic and/or chromatographic methods. Important points are also environmental awareness and disposal of by-products. Before each product is prepared, a discussion must be held. ECTS credits are assigned to the individual subject areas as follows: Inorganic chemistry 5.5 credits, organic chemistry 9.5 credits.

Master's lectures and courses
Subject of the course
The first part of this Lecture will introduce the concept of molecular recognition, overview major forces of molecular self-assembly and cover several important historical milestones of the field such as the recent Nobel Prize in Chemistry 2016. We will cover many textbook examples of self-assembled systems including molecular (crown ethers, cyclodextrine and calixarenes) as well as biological (proteins, DNA) systems and slowly go up in complexity. Following examples will present self-assembled systems of various dimentionalities: 0D (micelles, fullerenes), 1D (carbon nanotubes), 2D (self-assembled monolayers, Langmuir-Blodgett films, graphene) and 3D (block copolymers, liquid crystals). We will spend much time trying to classify and sort out non-covalent interactions (e.g. van der Waals forces) that are very imporant in the world of molecular self-assembly. At the end of this first part, we will look at the self-assembly of inorganic nanoparticles and talk about metal organic frameworks. The course will introduce you to a number of practical examples where molecular self-assembly made it way to applications and devices.
The second part of the Lecture will introduce you to various photoactive materials such as photovoltaics (PV), light emitting diodes (LED), lasers, photocatalysts and phosphors. The aim is to develop your understanding of the materials design and materials requirements for each of these applications. We will start by discussing the nature of the light-to-matter interactions and sort out the concepts or color, transparency and opaqueness, absorption and reflectance, refraction and birefringence to understand the principles and limitations of various photoactive materials. We will further link this knowledge with the band theory of solid state materials and review the concept of metals, semiconductors and insulators. Particular focus will be devoted to history, basic principles, materials, limitations and perspectives of solar cells, photocatalysis and light emitting diodes.

Other talks and lectures
In his talk, opens an external URL in a new window, Alexey Cherevan focuses on the idea of artificial photosynthesis – a process that aims to mimic the functions of biological systems by creating human-made materials able to convert water and carbon dioxide into useful chemicals relying solely on the energy of light. He discusses the capabilities and complexity of natural photosynthesis and shows how material scientists can be inspired by nature to recreate the process.
