Direct arylation polycondensation as simplified alternative for the synthesis of conjugated (co)polymers

Future application of conjugated (co)polymers, e.g. in electronic devices, requires the availability of up-scalable synthetic procedures. “Conventional” (hetero)aryl-(hetero)aryl coupling schemes often produce toxic or environmentally risky by-products. Here, so-called direct arylation schemes witho...

Description
Summary:Future application of conjugated (co)polymers, e.g. in electronic devices, requires the availability of up-scalable synthetic procedures. “Conventional” (hetero)aryl-(hetero)aryl coupling schemes often produce toxic or environmentally risky by-products. Here, so-called direct arylation schemes without use of organometallic reagents or related anion equivalents came in the focus of attention as simplified alternative to standard coupling procedures. Now, a couple of structurally defined conjugated (co)polymers can be generated in high yield and molecular weight via direct arylation polycondensation. The promising application potential of these materials as active component of organic solar cells has been demonstrated.
