Phenanthro[9,10-b]furan polymers and small molecules for electronic applications. The present invention relates to polymers comprising a repeating unit of the formula (I), (II), (VIII), (IX) and compounds of formula (VIII), or (IX), wherein Y, Y15, Y16 and Y17 are independently of each other a group of formula (I), or (II), and their use as organic semiconductor in organic electronic 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 (solar cells) and photodiodes.; |
