Direct Heteroarylation versus Stille Polycondensation Reaction for the Synthesis of TQ1 Conjugated Polymer
We report a facile synthesis of the well-known and highly promising conjugated polymer TQ1 using eco-friendly direct heteroarylation reaction. Optimization of the reaction conditions yielded the target polymer with good optoelectronic and charge-transport characteristics. The TQ1 polymer obtained in the direct heteroarylation reaction delivered power conversion efficiency of similar to 5% in organic bulk heterojunction solar cells, which matches well the characteristics of the reference devices assembled using TQ1 batch synthesized via conventional Stille polycondensation reaction. The obtained results highlight the potential of the direct heteroarylation reaction as an efficient and environment-friendly alternative to Stille cross-coupling in the design of high-quality semiconductor materials for organic electronics.
