Abstract: An organic semiconductor device selected from organic diodes, organic field effect transistors, and devices comprising an organic diode and/or organic field effect transistor and a method of producing such a device are provided. The organic semiconductor device comprises at least one semiconducting layer based on a diketopyrrolopyrrole (DPP) polymer. The semiconducting layer may effectively be protected against degradation by radiation and/or oxidation by adding at least one stabilizing agent selected from hydroxybenzophenones, hydroxyphenyl benzotriazoles, oxalic acid anilides, hydroxyphenyl triazines, hindered phenols and/or merocyanines to the DPP polymer layer. The stabilization is effective both during production and during usage of the device, while the device's electronic properties are retained. The stabilizing agent is preferably a UV absorbing agent or an antioxidant or anti-radical agent known from the field of organic polymer technology.

Abstract: A circuit arrangement comprises a first electronic component, which is an organic field-effect transistor. It comprises a source electrode (111), a drain electrode (112), a channel region (113) and a gate electrode (114). A second electronic component is electrically coupled to the first electronic component. A membrane (101) exhibits ion-conductivity between the channel region (113) and the gate electrode (114). The membrane also exhibits ion-conductivity in a section (121) of the membrane that is located between a first part of the second electronic component and a second part of the second electronic component.

Abstract: An organic field-effect transistor includes between an organic semiconductor layer (203) and a gate electrode (204) a polymer membrane (205) having a ion-conducting spatial area (206) between a channel region and the gate electrode. Due to the ion-conducting spatial area (206) a distance between the gate electrode and the organic semiconductor layer can be longer than that in an organic field-effect transistor according to the prior art.
