| abstract |
The present invention provides a process for preparing a solution or suspension containing (i) at least one dopant precursor, at least one organic material to be doped and a solvent, (ii) applying the solution or suspension onto a substrate and removing the solvent. (Iii) applying an activation energy to convert the dopant precursor into a dopant, wherein the dopant precursor is a dimer, oligomer, polymer, disspiro compound or polycycle of the dopant, The dopant precursor is directed to a method of making a doped organic semiconductor material that is decomposed into dopants by the application of activation energy. |
