Estimating the term…
The present invention relates to a conductive polymer material of poly(thio- or seleno-)phene type containing at least two distinct species of counteranion, including a first species which is an anionic form of sulphuric acid, and a second species of counteranion selected from triflate, triflimidate, tosylate, mesylate, perchlorate and hexafluorophosphate. The invention also relates to a process for preparing such a material and the use thereof as conductive film. The invention also targets a substrate coated at least partly by a film of a material as defined above, a device comprising a material as defined above as conductive material, and also the use thereof in the organic electronics, organic thermoelectricity, organic photovoltaic and organic photodetector fields.
A conductive polymeric material including a poly(thio or seleno)phene type polymer comprising at least two distinct kinds of counteranions, including a first kind of counteranion which is an anionic form of sulfuric acid, and a second kind of counteranion selected from the group consisting of triflate and triflimidate.
A process for increasing the conductivity of a polymeric material including a poly(thio or seleno)phene type polymer comprising at least one first kind of counteranion which is an anionic form of sulfuric acid, and a second kind of counteranion chosen from triflate and triflimidate, wherein the polymeric material is provided in the form of a film on a surface of a solid substrate, the process comprising contacting said film with an aqueous solution of a sulfur-comprising acid under conditions favorable to the immobilization of an anionic form of said acid within the polymeric material.
