| abstract |
The invention relates to novel conjugated polymers containing repeating units comprising a halogenated benzene ring, a silolobithiophene moiety, and a benzofused heteroaromatic moiety, to methods for their preparation and educts or intermediates used therein, to polymer blends, mixtures and formulations containing them, to the use of the polymers, polymer blends, mixtures and formulations as organic semiconductors in organic electronic (OE) devices, especially in organic photovoltaic (OPV) devices and organic photodetectors (OPD), and to OE, OPV and OPD devices comprising these polymers, polymer blends, mixtures or formulations. |
