| abstract |
The invention relates to novel organic semiconducting (OSC) polymers containing a polycyclic acceptor-donor-acceptor (A-D-A) type repeating unit, to methods for their preparation and educts or intermediates used therein, to compositions and formulations containing them, to the use of the polymers and compositions as organic semiconductors in, or for the preparation of, organic electronic (OE) devices, especially organic photovoltaic (OPV) devices, perovskite-based solar cell (PSC) devices, organic photo-detectors (OPD), organic field effect transistors (OFET) and organic light emitting diodes (OLED), and to OE, OPV, PSC, OPD, OFET and OLED devices comprising these polymers or compositions. |
