Course description and aims
The fields of optical functional materials, organic semiconductors, or organic opto-electronic devices require the basic knowledge of optical properties and photophysical processes of organic molecules and molecular complexes. With these applications in mind, the course uses the quantum-mechanical description of optical transitions to explain photophysical processes occurring on isolated organic molecules. Based on this knowledge, the course further explains both strong (exciton coupling) and weak (energy transfer) dipole-dipole interactions in molecular aggregates, examines the effect of external fields, the confinement of light, and introduces differences between organic materials and inorganic semiconducting nanostructures. As the advanced optical nanoscale characterization methods the course explains the principle of single-molecule spectroscopy, high-resolution optical spectroscopy and super-resolution microscopy. The course is given entirely in English.
Student learning outcomes
Within the broad field of soft matter physics, this course focuses on optical properties and optical function of organic materials. The aim of the course is to gain understanding of the basic photophysical properties and processes on organic molecules as well as on organic semiconductors and related opto-electronic devices. In addition, the course will introduce the latest optical methods for material nanoscale characterization, such as single-molecule spectroscopy, high-resolution optical spectroscopy and super-resolution microscopy.
The knowledge of basic optical properties, and especially, photophysical processes, is indispensable for the understanding of the basic principles of organic semiconductor-based devices, such as organic light-emitting diodes, organic solar cells, organic field-effect transistors or displays. The course starts with the description of optical transitions, and continues with photophysical processes, intermolecular interactions, the concept of excitons, and finally concludes with advanced optical nanoscale characterization methods.

Competencies that will be developed
| ✔ Specialist skills | ✔ Intercultural skills | Communication skills | Critical thinking skills | Practical and/or problem-solving skills |
Class flow
The first 15 minutes of each class will be used to review the contents of the previous class and to explain solutions of problems. The course itself is often based on theoretical quantum-mechanical treatment but this is supplemented with practical examples of the phenomena on real materials. Students are required to understand the contents of each lecture and review it for the next class.
