This chapter covers the structure-property relationships that control electrochemical properties (redox potentials), optical/colorimetric properties (electronic absorptions in the various redox states) and solubility/processability. Only polymers that are thin electrode-supported films are considered here. The chapter focuses on those properties most influenced by repeat unit structure alone: oxidation potentials and colour properties, along with solubility and processability. For a large majority of conjugated polymers in the chapter, the oxidation is of an electrode-supported polymer film. The chapter talks about the oxidative process, also called p-doping. There is a very small subset of polymers that exhibit reductive electrochromic behaviour via n-doping. The chapter further explains how properties of conjugated polymers applicable to electrochromics are manifested and altered. It also explains how chemists utilise synthetic design principles to tailor optical and electrochemical properties. The chapter concludes with a discussion on the processability of electrochromic polymers (ECPs).
