16. We emphasize that the present work focuses on the reversible molecular switching of a self-assembled monolayer on an optically transparent metal electrode. Therefore, the effects of the morphological features of the Pt substrate on the overall optical properties of the SAM would be out of the aim of the present study. Such effects will be the object of a forthcoming investigation.
