General description

We are committed to bringing you Greener Alternative Products, which adhere to one or more of the 12 Principles of Green Chemistry. This product is used in energy conversion and storage, thus has been enhanced for energy efficiency. Click here for more information.
Poly(3,4-ethylenedioxythiophene)-poly(styrenesulfonate) (PEDOT:PSS) is an organic semiconductor wherein conjugated PEDOT is doped with sulfonated PSS, which acts as a counter ion. PEDOT is responsible for the conduction mechanism and the hydrated colloidal solution formed by PSS.
PEDOT:PSS has high electrical conductivity and good oxidation resistance, the properties which make it suitable for electromagnetic shielding and noise suppression. Thus, the polymeric film formed possesses high transparency throughout the visible light spectrum and even in near IR and near UV regions, displaying virtually 100% absorption from 900-2,000 nm. No absorption maximum from 400-800 nm was observed.


PEDOT:PSS acts as an intrinsically conductive polymer, which can be coated on a variety of substrates and nanoparticles like fullerenes (C60) for the low-cost printing of electronics and optoelectronics based applications. Conductive hydrogels can be prepared by using PEDOT:PSS with polyethylene glycol-diacrylate, which can be potentially used in tissue engineering.
Virtually 100% absorption from 900-2,000 nm. No absorption maximum from 400-800 nm. Conductive polymer blend.

  5. Is a dried film of product 739316 (poly(3,4-Ethylenedioxythiophene)-poly(styrenesulfonate)) stable in air in a laboratory environment?

    Product 739316 (poly(3,4-Ethylenedioxythiophene)-poly(styrenesulfonate)) is susceptible to oxidation and photo degradation, however, our supplier has outlined that this concern is in reference to exposure to strong oxidizing agents and UV light in particular. The product when dried on target will be stable in a typical lab air environment, however, one will notice degradation and lack of conductivity when exposed to UV light, strong oxidizing conditions, heat, and or high humidity for extended periods of time.

  6. Why does product 739316, Orgacon IJ-1005, have a low pH?

    Orgacon IJ-1005 has a low pH because this ink is intended for use as an HIL (hole-injection layer) in OLED materials. Increasing pH would negatively affect the workfunction, but if you want to print on textiles to obtain conducting lines, you can slightly adjust the pH with amonia or an organic amine base. The ink is in water and typically needs to reach 130°C for drying.

  7. What can you tell me regarding the method of preparation of the PEDOT/PSS products, such as Products 768618 and 739316?

    The information on the molecular weights of the PEDOT and PSS used to make each batch is held as proprietary.The exact information on the relative amounts (by weight) of the PEDOT and PSS present in these polymers is also held as proprietary. There is a little more PSS than PEDOT; this is logical, since the formula weight for the monomeric equivalent in PSS (C7H6SO3) is a little higher than the formula weight for the monomeric equivalent in PEDOT (C6H4SO2).The solution, product 739316 is made in situ; it is not made from the dry pellets (product 768618).

New Conducting and Semiconducting Polymers for Plastic Electronics

In the emerging field of organic printable electronics, such as OLEDs and organic photovoltaics (OPVs), there is a significant need for improved organic conducting and semiconducting materials. This paper reports our recent progress in two fields: 1) the development of solvent-based dispersions of the intrinsically conducting polymer (ICP) poly(3,4- ethylenedioxythiophene) (PEDOT) and 2) the synthesis of new electron-deficient (n-type) semiconducting polymers.
