| 摘要 |
The invention relates to novel organic semiconducting compounds, which are small molecules or conjugated polymers, containing one or more isoindigo or thienoisoindigo based polycyclic units, to methods for their preparation and educts or intermediates used therein, to compositions, polymer blends and formulations containing them, to the use of the compounds, compositions and polymer blends as organic semiconductors in, or for the preparation of, organic electronic (OE) devices, especially organic photovoltaic (OPV) devices, organic photodetectors (OPD), Perovskite based solar cells, organic field effect transistors (OFET) and organic light emitting diodes (OLED), and to OE, OPV, OPD, OFET and OLED devices comprising these compounds, compositions or polymer blends. |

1. A compound comprising one or more divalent units of formula I wherein R1 on each occurrence identically or differently, denotes H or straight chain, branched or cyclic alkyl group with 1 to 30 C atoms in which one or more non-adjacent CH2 groups are optionally replaced, in each case independently from one another, by —O—, —S—, —C(O)—, —C(O)O—, —O—C(O)—, —O—CO(O)—O—, —SO2—, —SO3—, —NR0—, —SiR0R00—, —CF2—, —CR0═CR00—, —CY1═CY2— or —C≡C— in such a manner that O and/or S atoms are not linked directly to one another, and in which one or more H atoms are optionally replaced by F, Cl, Br, I or CN, or denotes monocyclic or polycyclic aryl or heteroaryl, each of which is optionally substituted with one or more groups Rs and has 4 to 30 ring atoms X is O or S, A1, A2, A3 denote, independently of each other, and on each occurrence identically or differently, a monocyclic or polycyclic aromatic or heteroaromatic group with 4 to 20 ring atoms that is optionally substituted by one or more groups RS, RS denotes, on each occurrence identically or differently, F, Br, Cl, —CN, —NC, —NCO, —NCS, —OCN, —SCN, —C(O)NR0R00, —C(O)X0, —C(O)R0, —C(O)OR0, —NH2, —NR0R00, —SH, —SR0, —SO3H, —SO2R0, —OH, —NO2, —CF3, —SF5, optionally substituted silyl, carbyl or hydrocarbyl with 1 to 40 C atoms that is optionally substituted and optionally comprises one or more hetero atoms, R0, R00 independently of each other denote H or optionally substituted C1-40 carbyl or hydrocarbyl, and preferably denote H or alkyl with 1 to 12 C-atoms, Y1, Y2 independently of each other denote H, F, Cl or CN, X0 denotes halogen, preferably F, Cl or Br, r, s are independently of each other 0, 1, 2, 3 or 4. |
