Course content

Advanced organic optoelectronic materials focuses on the structure-property relationships of some of the most identifiable different classes of materials that give them these properties that make them ideal candidates for optoelectronic applications such as chemical sensors, molecular switches and machines, next-generation batteries, organic solar cells or artificial intelligence. Through the lens of organic chemistry the course will attempt to elucidate the various techniques by which a synthetic chemist can enrich the properties and maximize their potential and furthermore, on how chemical functionalization paves the way for their successful integration into applications The subject will first focus on the main different classes of organic electronic materials, namely conjugated polymers, small molecule semiconductors and carbon nanostructured materials (fullerenes, carbon nanotubes and graphene).

Then various structure-property relationships will be analyzed towards various next-generation applications (i.e. nanomedicine, solar cells, batteries etc.) in order to facilitate understanding of operating principles and their link to the material properties.

Main concepts and fundamental material physics will be explained, along with key-strategies for their synthesis. The main focus will be on the wide variety of different functionalization routes that affect the properties of the resulting material. Various synthetic strategies employing "green chemistry for sustainable synthetic approaches will be analyzed.

The attempted structure-property relationship will allow for a more informed decision on the synthesized molecule relative to the targeted application. Special attention will be given on the different characterization methods that exist in order to analyze these different material properties. (e.g. Steady State and Time-resolved Optical Spectroscopies, Electrochemistry, SEM, AFM)

Keywords: Semiconducting polymers, Fullerenes, Carbon Nanotubes, Graphene, Chemical Tailoring, Organic Solar Cells, Organic LEDs, Batteries, Fuel Cells, Nanomedicine.
