| abstract |
The present invention relates to an oligomer of the formula □(I), and as an organic semiconductor in an organic device, in particular in an organic photovoltaic device (solar cell) and a photodiode, or in the presence of a diode and/or Use in devices with airport effect transistors. When the oligomers of the present invention are used in an organic field effect transistor, an organic photovoltaic device (solar cell), and a photodiode, high energy conversion efficiency, excellent field effect mobility, good on// Off current ratio and / or excellent stability. |
