The monomers, 2,6-di(furan-2-yl)-4,4-dioctyl-4H-silolo[3,2-b:4,5-b'] dithiophene (FSiF), 4,4-dioctyl-2,6-di(thiophen-2-yl)-4H-silolo[3,2-b:4,5-b']dithiophene (TSiT) and 4,4-dioctyl-2,6-di(selenophen-2-yl)-4H-silolo[3,2-b:4,5-b'] dithiophene (SeSiSe) were polymerized electrochemically via potential cycling in acetonitrile-tetrabutylammonium perchlorate electrolytic medium. Optical and electrochemical properties of the monomers and their corresponding polymers were investigated and it was found that oxidation potentials of the monomers and optical properties of both monomers and their polymers showed slight variations depending on the heteroatom present in the donor unit.
