  • Diketopyrrolopyrrole oligomers and compositions, comprising diketopyrrolopyrrole oligomers
    Patent number: 9209412
    Abstract: The present invention relates to compositions, comprising (a) a compound of the formula (I), and (b) a polymeric material, to specific oligomers of the formula I, and their use as organic semiconductor in organic devices, especially in organic photovoltaics (solar cells) and photodiodes, or in a device containing a diode and/or an organic field effect transistor. High efficiency of energy conversion, excellent field-effect mobility, good on/off current ratios and/or excellent stability can be observed, when the compositions, or oligomers according to the invention are used in organic field effect transistors, organic photovoltaics (solar cells) and photodiodes.
