Abstract: Various embodiments provide a method of forming an organic inverter including a first transistor and a second transistor. The method may include providing a substrate with a dielectric layer formed on top of the substrate; depositing a first semiconductor polymer layer on a first region of the dielectric layer; forming a first electrode and a second electrode on the first semiconductor polymer layer, thereby forming the first transistor located at the first region of the dielectric layer; forming a plurality of grooves on a surface of a second region of the dielectric layer; depositing a second semiconductor polymer layer on the second region of the dielectric layer; and forming a first electrode and a second electrode on the second semiconductor polymer layer, thereby forming the second transistor located at the second region of the dielectric layer.

Abstract: A method of synthesizing a water-dispersible conductive polymeric composite comprising mixing an aqueous suspension comprising optionally substituted azulene monomers and a dopant precursor such as polystyrene sulfonic acid with an oxidizing agent and a catalyst to form a doped poly(azulene) suspension wherein the poly(azulene)/dopant molar ratio is 1:1 to 1:6. The doped poly(azulene) suspension is then contacted with acidic and basic resins to remove the oxidizing agent and catalyst. The resulting suspension is then filtered through a membrane such as polyvinylidene fluoride (PVDF) to afford a purified suspension comprising the water-dispersible conductive polymeric composite. A water-dispersible conductive polymeric composite comprising an optionally substituted poly(azulene) doped by a dopant such as polystyrene sulfonate wherein the poly(azulene)/dopant molar ratio is 1:1 to 1:6 is also disclosed.
