Abstract
The instant invention relates to a new method for the synthesis of monomers and their use inter alia in the manufacture of semiconductive polymers. Monomers, in particular, asymmetric monomers, such as asymmetric fluorene compounds, are valuable material in the manufacture of semiconductive polymers. The know methods for producing asymmetric monomers, such as asymmetric fluorene compounds, are expensive due to the formation of by-products.The method according to the present invention avoids the formation of such by-products and is described in more detail in claims 1 to 14.
