Figure 5. Spectroelectrochemistry of PT (A), PTT (B) and PDTT (C) on ITO coated glasses in CH3CN-Bu4NPF6, chromaticity diagram (Commission internationale de l'éclairage, CIE 1931) and photograph of polymers in oxidized and reduced states. PT: Polythiophene; PTT: poly(thieno[3,2-b]thiophene); PDTT: poly(dithieno[3,2-b:2’,3’-d]thiophene); ITO: indium tin oxide.
