    摘要: Polyurethanes having hyperbranched structures, selected from hyperbranched polyurethanes containing at least one pigment affinity group and modified hyperbranched polyurethanes, are used as polymeric dispersing additives for pigments. A preferred process for preparing modified polymeric dispersing additives comprises reacting a hyperbranched polyurethane having from 2 to 100 NCO groups and a molar mass of from 500 to 50,000 g/mol with one or more polyether derivatives.

    摘要: A terrylene compound of formula I: wherein R1 to R4 are each independently an unsubstituted or substituted alkyl, aryl, thiophenyl or oligothiophenyl group, or a hydrogen atom. Two adjacent radicals selected from R1 to R4, 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.
