Molecular Opto-electronics

The incorporation of photo or thermo molecular switches in thin films is intensively investigated because of their possible applications as memory devices, for optics or gas storage. Among the switchable materials, spin-crossover (magneto and thermo-chromic) complexes and photochromic organic materials are currently studied in our team. Below is an example showing thin films of photo-chromic materials, for which the conductivity is modulated by the state of the photo-isomer.
