Electrochemical properties of self-assembled monolayers (SAMs) of a new quinone-based chromophore will be discussed. A modified electrode surface will be used to attach the chromophore to electrodes via chemisorption or physisorption. A thiol group will be utilized to tether the chromophore to a gold electrode to measure its electrochemical properties through chemisorption. In order to record optical and electrochemical measurements, the compound will also be attached to a transparent electrode such as indium tin oxide (ITO) or fluorine-doped tin oxide (FTO) through physisorption using phosphonic acid linkers. Electrochemical characteristics of both physisorbed and chemisorbed quinone chromophores will be compared. This functionalization and measurement will help us build an electrochromic device (ECD) with the aforementioned quinone chromophore.
