摘要:
The invention relates to compositions which include: (a) a polythiophene containing repeating units represented by the following general formula (I), wherein X represents, for example, —CH2—CH(CH2—O—(CH2)4SO3−H+)—; and (b) further polymers, that are different than polythiophene (a), and which contain SO3− M+ or COO−M+ groups. Also disclosed are electroluminescing (EL) arrangements that contain hole-injecting layers which include such compositions.
摘要:
The invention relates to a process for producing conductive coatings containing a dispersion or solution comprising at least one optionally substituted polythiophene, at least one polyanion, water, at least one solvent and at least one basic additive by means of inkjet printing, wherein the pH of the aqueous dispersion or solution is adjusted to a value between 2 and 10 by means of at least one basic additive. The invention also relates to a conductive coating and the use thereof.
摘要:
Processes comprising: (a) providing a substrate; and (b) forming a conductive structured polymer layer on a surface of the substrate, wherein forming the conductive structured polymer layer comprises applying at least one conductive polymer comprising a polycation and at least one polyanion having a mean molecular weight Mw of 1,000 to 100,000 g/mol using a lift-off process; and structured conductive layers prepared thereby.
摘要:
The present invention relates to novel processes for preparing an aqueous or nonaqueous dispersion or solution comprising at least one conductive polymer and at least one polyanion, characterized in that the polymerization is performed at a pressure below atmospheric pressure, to aqueous or nonaqueous dispersions or solutions prepared by this process and to the use thereof.
摘要:
Polythiophenes which are soluble or dispersible in anhydrous or low-water-content solvents can be prepared if they are prepared in anhydrous or low-water-content solvents and a phase-transfer catalyst is added during the reaction.
