Abstract

The invention relates to the preparation of aryl-aryl coupled compounds and materials. These materials play an important role in industry, for example as liquid crystals, pharmaceuticals and agrochemicals, to mention just a few application areas. These compounds, in particular, are also of major importance especially in the high-growth area of organic semi-conductors (for example, applications in organic or polymeric light-emitting diodes, organic solar cells, organic ICs).
