Optical Read‐Out of the Electrical Switching of Cobalt‐Terpyridine‐BODIPY Molecules Immobilized as Single Layer on ITO

Abstract

Abstract A single layer of a dyad made of a cobalt(II) bis‐terpyridine complex functionalized with a Boron‐dipyrromethene (BODIPY) fluorophore on transparent Indium Tin Oxide (ITO) electrode is prepared. A modulation of the photoluminescence intensity of the fluorophore upon the application of an electric stimulus on the ITO electrode that supports 10 picomoles of molecules is demonstrated. The intensity of the fluorescence intensity decreases when the cobalt is at the oxidation state +III, due to Co III oxidative quenching of BODIPY emission that has a higher driving force than the Co II reductive quenching initially responsible for the low fluorescence intensity of the chemisorbed dyad.
