Electrochemical Switching of Chromogenic Monolayers Self-Assembled on Transparent Platinum Electrodes

Transparent, ultrathin Pt electrodes permit the simultaneous electrochemical and spectroscopic investigation of self‐assembled monolayers of electrochromic compounds. Voltage stimulations applied to the Pt substrate reversibly alter the redox state of the chemisorbed molecules and, hence, modulate the intensity of the light transmitted through the Pt/monolayer assembly (see Figure).
