Abstract
The present invention relates to a method for preparing doped organic semiconductor materials as well as a formulation which may be utilized in that method. The doped organic semiconductor materials are prepared by preparing a solution or suspension containing at least one dopant precursor, at least one organic material to be doped, and a solvent. The solution or suspension is then applied onto a substrate. After removing the solvent, the dopant precursor is converted into a dopant by application of activation energy. The dopant precursor, which is a dimer, oligomer, polymer, dispiro compound, or polycycle, is cleaved by the application of activation energy.
