  • Polymers based on fused diketopyrrolopyrroles
    Patent number: 9698348
    Abstract: The present invention relates to polymers comprising one or more (repeating) unit(s) of the formula (I), wherein Y is a group of formula (II); and their use as IR absorber, organic semiconductor in organic devices, especially in organic photovoltaics and photodiodes, or in a device containing a diode and/or an organic field effect transistor. The polymers according to the invention can have excellent solubility in organic solvents 10 and excellent film-forming properties. In addition, high efficiency of energy conversion, excellent field-effect mobility, good on/off current ratios and/or excellent stability can be observed, when the polymers according to the invention are used in organic field effect transistors, organic photovoltaics and photodiodes.
