Polymers containing a repeating unit of the formula —[Ar—Y—Ar′]— (V), and compounds of formula R 10 —Ar—Y—Ar′—R 10′ (I), where Y is a group of formula n n n n n n n n n n and organic devices containing the polymers. The polymers and compounds have excellent solubility in organic solvents and excellent film-forming properties. In addition, high efficiency of energy conversion, excellent field-effect mobility, good on/off current ratios and/or excellent stability can be observed, when the polymers and compounds are used in organic field effect transistors, organic photovoltaics and photodiodes. |
