Abstract:
The present invention relates to polymers comprising one or more (repeating) unit(s) of the formula *A-D* (I), or a polymer of formula *A-DxB-Dy* (II), or *A-DrB-DsA-EtB-Eu (III), and their use as organic semiconductor in organic devices, especially in organic photovoltaics (solar cells) and photodiodes, or in a device containing a diode and/or an organic field effect transistor. 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 organic field effect transistors, organic photovoltaics (solar cells) and photodiodes.
