Among various main-chain conjugated polymers, one of the most practically used may be the poly(3,4-ethylenedioxythiophene) (PEDOT)-poly(styrenesulfonate) (PSS) mixture [121-124], PEDOT is a polythiophene derivative that can be doped using sulfonic acid including PSS and redox active metals. Since the fraction of PSS is higher than that of PEDOT in commercial aqueous solutions, the material is acidic. Also due to long main-chain conjugation PEDOT-PSS shows deep blue color. These two characteristics somewhat limit applications of PEDOT-PSS. [Pg.37]

As an alternative to pendent sulfonate groups, polythiophene derivatives which possess pendent carboxylic acids have been investigated. The lower acidity of the carboxylic acid functionality (/7ATa 4.8) compared to... [Pg.843]
