Annotation: The course focuses on the specialized field of organic electronics - an interdisciplinary area integrating organic chemistry, materials science, physics, and electronics. Students will gain an overview of the synthesis and characterization of selected molecules, become familiar with examples of compounds commonly used in the field, and explore their applications in electronic sensors and other components. 1. Introduction to organic electronics: OLEDs, field-effect transistors (FET), memristors, organic solar cells; organic dyes (fluorescent, non-fluorescent, chiral, etc.), conducting polymers, natural functional molecules, theoretical calculations. 2. How to create a molecule: synthesis (solubility, reaction notation, concepts of asymmetric synthesis, chiral compounds, organometallic complexes, etc.); isolation from natural sources (purification, methods, availability); CVD (polymer synthesis, insoluble compounds). 3. Characterization I: methods supporting synthesis (NMR, solid-state NMR, FTIR and ATR-FTIR, chromatography, optical characterization, melting point). 4. Characterization II: electronic properties and orbitals (cyclic voltammetry, XPS, inverse XPS, UPS, practical examples, thickness determination, collaboration opportunities). 5. Characterization III: optical properties and molecular ordering (UV-VIS, ATR-FTIR, VASE, XRD and GIWAXS, SAXS, AFM - overview of techniques). 6. Characterization IV: conductivity and magnetism (electrode geometry, Hall effect, conductivity, magnetoconductivity, 1D-3D transport, free electrons and color formation, VSM, AC magnetometry, types of magnetism, experimental challenges). 7. Molecules I: conducting polymers and SAMs (doping, optical properties, polaron/bipolaron theory, characterization methods, chiral conducting polymers, self-healing). 8. Molecules II: optically active materials (indigoids, vat dyes, azo dyes, helicenes, cis-trans isomerization and isosbestic points, push-pull substituents, quantum dots). 9. Molecules III: natural compounds and edible electronics (substrate materials - shellac, cellulose; dielectrics - resins, caffeine; semiconductors ? quinacridone, epindolidione; biodegradation, artificial retina). 10. Molecules IV: organometallic complexes (biological role and dyes/vitamins, porphyrins and corroles, synthetic complexes, chiral complexes, role of metals, catalysis). 11. Electronics I: OLEDs and solar cells (architectures, operating principles; types of OLEDs, types of solar cells; literature examples - imperceptible electronics, etc.). 12. Electronics II: transistors and memristors (OFET - properties and materials, memristors - geometry, components, operating principles, literature examples). Outcomes: Upon completion of the course, students will understand the fundamentals of organic electronics and the operating principles of key devices such as OLEDs, transistors, memristors, and solar cells. They will acquire knowledge of the synthesis and characterization of organic and organometallic molecules, learn to apply fundamental physico-chemical methods to analyze their properties, and develop an understanding of the relationships between structure, properties, and function of these materials.
