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.
本发明涉及含有重复单元式(I)、(II)、(VIII)、(IX)的聚合物和式(VIII)或(IX)的化合物,其中Y、Y15、Y16和Y17分别独立地是式(I)或(II)的基团,并将其用作有机半导体在有机电子器件中的应用,特别是在有机光伏和光电二极管中,或在包含二极管和/或有机场效应晶体管的器件中。本发明中的聚合物和化合物可以在有机溶剂中具有优异的溶解性和优异的成膜性能。此外,当本发明中的聚合物和化合物用于有机场效应晶体管、有机光伏(太阳能电池)和光电二极管时,可以观察到高能量转换效率、优异的场效应迁移率、良好的开/关电流比和/或优异的稳定性。
