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: A synchronized piezoelectric and luminescence (SPL) material includes a core layer including light-emitting particles and a shell layer which is attached onto a surface of the core layer and includes ligands having a piezoelectric property. Therefore, a piezoelectric property and a luminescent property can be simultaneously implemented using a single SPL material in which piezoelectric ligands and light-emitting particles are chemically coupled.
