Focus Area
Our goal is the study of several Polycyclic Aromatic Hydrocarbons based photoswitches for molecular electronics. This implies the study of photoisomerization processes and the further determination of the molecular conductance for the different switch forms. The results obtained in the project will allow proposing cutting-edge designs of molecular photoswitches that may mimic more complex active devices within electronic systems.
