Research Progress in Conjugated Polymer Prepared by Direct (Hetero) Arylation Polycondensation

In recent years, polycondensation via direct arylation has become widely recognized as an atom-economic and environmentally friendly method to prepare it-conjugated polymers, which drawing lots of researchers attention. Comparing with traditional cross-coupling reactions, the direct arylation of polymerization has many advantages, such as fewer synthetic steps, less time, higher monomer purity, less harmful substances on human beings and the environment, etc. Herein, the latest progress in direct arylation polycondensation about preparing different types of conjugated polymers was summarized. At the same time, the reaction mechanism of some factors influence on direct arylation polycondensation reaction was explored, including the polymerizable monomer, the reaction time, solvent, etc. The suitable for direct arylation of polycondensation reaction monomer characteristics was gained by comparing the data of polymerization product.
