Learning outcomes
The aim of the course is to give students a complete overview on the main classes of organic materials, with particular relevance to their preparation, their properties and to their applications. Competences will be acquired also in the field of biomaterials(proteins, carbohydrates, etc.). In particular, students will be able to understand the connections between the chemical structure and the technological peculiarities of the most important organic materials (dyes and pigments, luminescent and chromogenic materials, liquid crystals, ) and to evaluate the possible applications.
