Within the research topic “unimolecular electronics and spintronics”, we are working on the synthesis of organic electroactive materials and organic radicals to integrate them in molecular electronic devices. We are also interested in the emerging field of molecular spintronics.

The development of novel molecular switches in solution and on surface as self-assembled monolayers (SAMs) is one of the primary research topics of the organic electronics group. We are using as active component different organic electroactive molecules and organic radicals.

In the organic electronic group we have available the necessary advanced facilities for preparing and processing organic materials as well as for characterizing and fabricating organic/molecular electronic devices.
