The invention relates to polymers containing repeating units of the formula (I) and organic semiconductors, in particular organic semiconductors in organic photovoltaic elements and photodiodes, or in elements containing diodes and / or organic field-effect transistors. Regarding its use. The polymers according to the invention can have excellent solubility in organic solvents and excellent film-forming properties. Furthermore, when the polymer according to the present invention is used in organic field effect transistors, organic photovoltaic devices (solar cells) and photodiodes, high energy conversion efficiency, excellent field effect mobility, good on / off current ratio. And / or excellent stability can be observed. |
