[0332] Preparation Example 1: Preparation of PANI conductive polymer composition solution

[0333] PSSA-g-PANI (polystyrenesulfonic acid grafted polyaniline) was synthesized as a self-doping conductive polymer using a synthetic method known in the art [W.J.Bae et al. Chem.Comm., pp 2768-2769, 2003]. At this point, the weight ratio of PSSA polymer chains to grafted PANI chains was 1:0.15. The number average molecular weight of PSSA-g-PANI was 35,000.

Abstract

Provided is a conducting polymer composition including a conducting polymer and an ionic conjugated polymer. The conducting polymer composition includes the ionic conjugated polymer having a conjugated structure, in addition to the conducting polymer, and thus, can enhance hole injection and transport capability. Furthermore, ionization potential and work function can be easily adjusted by chemically tuning the backbone of the ionic conjugated polymer. In addition, the conducting polymer composition can be dissolved in water, alcohol, or a polar organic solvent, thereby enabling a solution process and rendering spin-coating easier.

Description

technical field [0001] The present invention relates to conductive polymer compositions and electronic devices comprising the same. More particularly, the present invention relates to a conductive polymer composition which is improved in hole injection and transport capabilities, has good coating properties, and can be easily combined with other organic polymers due to uniform dissolution in water or organic solvents. Blending easily, and easily adjusting conductivity and work function, and related to electronic devices including the conductive polymer composition and thus having high efficiency and long life. Background technique [0002] In general, optoelectronic devices are defined as devices that convert light energy into electrical energy and vice versa. Optoelectronic devices include organic light-emitting devices, photovoltaic devices, electrochromic devices, electrophoretic devices, (photo)-transistors, and the like. In order to increase the efficiency of optoelec...
