Abstract: The present invention relates to polymers comprising a repeating unit of the formula (I) and their use as organic semiconductor in organic devices, especially a diode, an organic field effect transistor and/or a solar cell, or a device containing a diode and/or an organic field effect transistor, and/or a solar cell. The polymers according to the invention 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 semiconductor devices or organic photovoltaic (PV) devices (solar cells).

Abstract: A polymer includes repeating unit(s) of the formula (I). a, b, c, d, e and f are 0, 1, 2, or 3. Ar1 and Ar1′ are independently of each other a group of formula (AR1). Ar2, Ar2′, Ar3, Ar3′, Ar4 and Ar4′ are independently of each other a group of formula (AR2). The polymer is preferably a co-polymer.
