The invention relates to novel conjugated polymers containing one or more units based on dithieno[3,2-c;2′,3′-e]azepine-4,6-dione that is fused to further aromatic rings, 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. 3. The polymer according to claim 1 , characterized in that it comprises one or more units selected from the following formulae{'br': None, 'sup': 1', '2', '3, 'sub': a', 'b', 'c', 'd, '—[(Ar)—(U)—(Ar)—(Ar)]—\u2003\u2003IIa'}{'br': None, 'sub': b', 'a', 'b', 'c', 'd, 'sup': 1', '2', '3, '—[(U)—(Ar)—(U)—(Ar)—(Ar)]—\u2003\u2003IIb'}whereinU is a unit of formula I,{'sup': 1', '2', '3', 'S, 'Ar, Ar, Arare, on each occurrence identically or differently, and independently of each other, arylene or heteroarylene that is different from U, preferably has 5 to 30 ring atoms, and is optionally substituted, preferably by one or more groups R,'}{'sup': S', '0', '00', '0', '0', '0', '0', '00', '0', '0, 'sub': 2', '3', '2', '2', '3', '5, 'Ris on each occurrence identically or differently F, Br, Cl, —CN, —NC, —NCO, —NCS, —OCN, —SCN, —C(O)NRR, —C(O)X, —C(O)R, —C(O)OR, —NH, —NRR, —SH, —SR, —SOH, —SOR, —OH, —NO, —CF, —SF, optionally substituted silyl, carbyl or hydrocarbyl with 1 to 40 C atoms that is optionally substituted and optionally comprises one or more hetero atoms,'}{'sup': 0', '00, 'sub': '1-40', 'Rand Rare independently of each other H or optionally substituted Ccarbyl or hydrocarbyl, and preferably denote H or alkyl with 1 to 12 C-atoms,'}{'sup': '0', 'Xis halogen, preferably F, Cl or Br,'}a, b, c are on each ...
