The invention relates to a method for the production of doped organic semi-conductor materials with increased charge carrier mobility and effective charge carrier mobility by doping with a doping agent. The doping agent is produced, essentially, by electrocrystallisation in a first step and is selected from a group of organic compounds having a reduced oxidation potential. An organic semi-conductor material is doped with the doping agent in a second step. The invention also relates to doped organic semi-conductor materials with increased charge carrier mobility and effective charge carrier mobility which are produced according to the above-mentioned method. The invention further relates to an organic diode comprising doped organic semi-conductor materials which are produced according to the above-mentioned method.
