Abstract: The present invention relates to the technical field of photoelectric materials, and in particular, to an alcohol dispersion of a conductive polyethylenedioxythiophene, and a method for preparing same and use of same. The present invention comprises a conductive polyethylenedioxythiophene and an alcohol, and the conductive polyethylenedioxythiophene comprises a polyethylenedioxythiophene cation and a fluorinated sulfonic acid ionomer counter anion. The present invention prepares a PEDOT alcohol dispersion by using an alcohol-dispersible highly fluorinated sulfonic acid ionomer as a counter anion to replace PSS, solving the hygroscopicity problem in conventional aqueous dispersions, and solving the problem that a conventional conductive aqueous dispersion of polyethylenedioxythiophene cannot be evenly applied on a hydrophobic surface due to high surface tension. The present invention has a simple synthesis process and is applicable to different substrates and different types of optoelectronic devices, thermoelectric devices, electrochromic thin films, and antistatic coatings, thus having broad prospects.

Abstract: Thin films of organic semiconducting material comprising perylene diimide small molecules with pyrrolic N—H bonds. Films are prepared using green solvents including water and alcohols. The films can be solvent-resistant and generally range in thickness from 10 to 1000 nm. Perylene diimide molecules are dissolved in solvent by addition of a base to polarize the pyrrolic N—H bond believed to generate an ionic salt in alcohol or aqueous solution. Devices containing such films are provided. Methods of making films and methods of using films in OPV device applications and in amine sensors are provided.
