Learning outcomes
|
After completing the course, students will have a basic understanding of the relationship between UV-VIS radiation and matter, the relationship between the structure of dyes and their affinity to colored substrates. Students will also gain in-depth knowledge in the field of organic dye synthesis, including the industrial processes. Students will also gain knowledge related to the application of dyes to various materials.
The student will be instructed on basics of quantum physics and relationships between structure and colour of organic molecules.
