Abstract
A conducting polymer, the conducting polymer composition further including an ionomer, and an organic optoelectronic device including the conducting polymer or the composition are provided. The conducting polymer according to the embodiments of the present invention is a self-doped conducting polymer in which conducting polymer chains are grafted in a polyacid. The conducting polymer composition to the present invention is manufactured by blending the self-doped conducting polymer with an ionomer having a physical cross-linking property thereto, and thus they are homogeneously dissolved in water or organic solvents. The conducting polymer and the composition have a good film-forming property and can be easily blended with other organic polymers, and conductivity and a work function thereof is easily controlled according to the content of the ionomer. Also, optoelectronic devices including the conducting polymer composition have high efficiency and a long lifetime.
