A terrylene compound of formula I:
wherein R
1
to R
4
are each independently an unsubstituted or substituted alkyl, aryl, thiophenyl or oligothiophenyl group, or a hydrogen atom. Two adjacent radicals selected from R
1
to R
4
, together with the carbon atoms of the benzene ring to which they are bonded, may also form a fused ring system having 1 to 8 additional rings. With the carbon atoms to which it is bonded, A forms a fused monocyclic, dicyclic, tricyclic, tetracyclic, pentacyclic or hexacyclic ring system which optionally contains one or more independently selected substituents. A process for preparing the terrylene compound. An organic solar cell with a photoactive region including at least one organic donor material in contact with at least one organic acceptor material, the donor material and the acceptor material forming a donor-acceptor heterojunction, and the photoactive region including at least one such terrylene compound.

A terrylene compound of the formula I and processes for preparation thereof are disclosed, (I) in which R1, R2, R3 and R4 are each independently selected from hydrogen and in each case unsubstituted or substituted alkyl, aryl, thiophenyl and oligothiophenyl; or in each case at least two adjacent radicals selected from the R1, R2, R3 and R4 radicals, together with the carbon atoms of the benzene ring to which they are bonded, may also be a fused ring system having 1, 2, 3, 4, 5, 6, 7 or 8 further rings, and A with the carbon atoms to which it is bonded is a fused monocyclic, dicyclic, tricyclic, tetracyclic, pentacyclic or hexacyclic ring system which optionally bears one or more independently selected substituents. Further disclosed is an organic solar cell with a photoactive region which comprises at least one organic donor material in contact with at least one organic acceptor material, wherein the photoactive region comprises at least one such terrylene compound.
