Abstract
Synthesis, isolation and characterization of diketopyrrolopyrrole (DPP) dimers are described. These derivatives were prepared starting from symmetric or asymmetric DPP 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-chemical calculations.
