Direct (Hetero)arylation Polymerization: Trends and Perspectives
Conjugated polymers have attracted much attention in recent years, as they can combine the best features of metals or inorganic semiconducting materials (excellent.electrical and optical properties) with those of synthetic polymers (mechanical flexibility,, ample process and loW,Cost production), thereby creating altogether new scientific synergies and technological opportunities. In the search for more efficient synthetic methods for the preparation of conjugated polymers, this. Perspective reports advances in the field of direct (hetero)arylation polymerizatiort. This recently ,developed polymerization method encompasses the formation of carbon carbon bonds between simple (hetero)arenes and (hetero)aryl halides, reducing, both the number of synthetic steps and the production of organometallic byproducts. Along these lines, we describe the most general and adaptable reaction conditions for the preparation of high-molecular-weight, defect-free conjugated polymers. We also discuss the bottleneck presented by the utilization of certain brominated thiophene units and propose some potential solutions. It is, however, firmly believed that this polymerization Method will become a versatile tool in the field of conjugated polymers by providing a desirable atom-economical alternative to standard cross-coupling polymerization reactions.
