The invention relates to new conjugated semiconducting polymers containing thermally cleavable side groups. The thermally cleavable side groups are selected from among carbonate groups and carbamate groups. By thermally cleaving side groups, the solubility or the polymers can be reduced in a targeted manner. The polymers are used as semiconductors in organic electronic (OE) devices, especially in organic photovoltaic (OPV) devices, organic photodetectors (OPDs), organic light emitting diodes (OLEDs), and organic field effect transistors (OFETs).

Conjugated polymers

A method of producing an optoelectronic device includes A) providing a substrate, B) applying a first electrode to the substrate, C) applying a first organic layer stack to the first electrode, D) producing a charge-generating layer stack on the first organic layer stack, E) applying a second organic layer stack to the charge-generating layer stack, and F) applying a second electrode to the second organic layer stack, wherein step D) includes D1) applying a solution of a first metal oxide precursor to the first organic layer stack, D2) generating a first charge-generating layer comprising a first metal oxide, D3) applying a solution of a second metal oxide precursor to the first charge-generating layer, and D4) generating a second charge-generating layer comprising a second metal oxide.
