Stas, Sara published the artcileStraightforward access to diketopyrrolopyrrole (DPP) dimers, Formula: C20H28B2O4S2, the publication is Dyes and Pigments (2013), 97(1), 198-208, database is CAplus.
Synthesis, isolation and characterization of diketopyrrolopyrrole (DPP) dimers are described. These derivatives were prepared starting from sym. or asym. diketopyrrolopyrrole monomers through Pd-catalyzed homocoupling, Yamamoto coupling or Suzuki coupling. The spectroscopic properties of these newly synthesized DPP dimers were investigated and were supported by quantum-chem. calculations
