| Abstract | This article describes the successful transfer of the Suzuki cross-coupling (SCC) reaction to polymer synthesis, one of the major developments within the last decade of polymer synthesis. The polymers prepared by Suzuki polycondensation (SPC) and its Ni-catalyzed reductive counterpart are soluble and processable poly(arylene)s which, because of their rigid and conjugated backbones, are of interest for the materials sciences. Achievable molar masses easily compete with those of traditional polyesters and polyamides. Insight is also provided into some synthetic problems associated with the transfer of SCC from low molar mass organic to high molar mass polymer chemistry by addressing issues like monomer purity, stoichiometric balance, achievable molar masses, and defects in the polymer structure. Although the emphasis of this article is on the synthetic and structural issues, some potential masses, and defects in the polymer structure. Although the emphasis of this article is on the synthetic and structural issues, some potential applications of the polyarylenes obtained are briefly touched upon, too. Together with the enormous developments in the areas of metallocene, ring-opening-metathesis, and acyclic diene metathesis polymerization the success of SPC impressingly underlines the increasing importance of transition metal-catalyzed CC bond forming reactions in polymer synthesis. |
