    Abstract: The present invention relates to polymers comprising a repeating unit of the formula—[Ar3]c—[Ar2]b—[Ar1]a—Y(R1)n1 (R2)n2—[Ar1′]a—[Ar2′]b′—[Ar3′]c′— (I), wherein γ is a bivalent heterocyclic group, or ring system, which may optionally be substituted, Ar1, Ar1′Ar2, Ar2′, Ar3 and Ar3′ are independently of each other a C6-C24 arylen group, which can optionally be substituted, or a C2-C30 heteroarylen group, which can optionally be, Formula (1), substituted; at least one of R1 and R2 is a group of formula (II); and their use as organic semiconductor in organic devices, especially in organic photovoltaics and photodiodes, or in a device containing a diode and/or an organic field effect transistor. The polymers according to the invention can 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 according to the invention are used in organic field effect transistors, organic photovoltaics and photodiodes.
