The present invention relates to polymers comprising one or more (repeating) unit(s) of the formula (I), and compounds of formula (III), wherein Y, Y15, Y16 and Y17 are independently of each other a group of formula and their use as IR absorber, 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 and compounds 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 and compounds according to the invention are used in organic field effect transistors, organic photovoltaics and photodiodes.
