Abstract

The invention relates to novel conjugated polymers containing one or more [1,2,5]Thiadiazolo[3,4-e]isoindole-5,7-dione (TID) repeating units, 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, or for the preparation of, organic electronic (OE) devices, especially organic photovoltaic (OPV) devices and organic photodetectors (OPD), and to OE, OPV and OPD devices comprising, or being prepared from, these polymers, polymer blends, mixtures or formulations.
