Abstract
A dispersion, and a film and optoelectronic devices formed from the dispersion are provided. The dispersion comprising conducting polymer containing particles having a particle size of less than 450 nm, wherein the conducting polymer comprises substituted or unsubstituted, uncharged or charged polymerized units of thieno[3,4-b]thiophene, and wherein a film drop cast from the dispersion has a conductivity from 10−1 to 10−6 S/cm measured using the four point probe method.
