| Outline of Final Research Achievements |
Polycondensation via direct arylation of C-H bond in aromatic monomers afforded the corresponding conjugated polymers. However, the C-H functionalization sometimes occurs at undesired positions of the aromatic monomers, which affords the irregular structure in the polymer chains. To suppress the undesired side reactions, we focused on development of site-selective direct arylation polycondensation. The introduction of directing group into the aromatic monomer was effective for ortho-selective C-H bond functionalization and gave well-defined conjugated polymers. On the other hand, we examined the relationship between the reaction conditions and the nature of thiophene monomers; the optimal reaction conditions were applicable to site-selective direct arylation polycondensation and afforded well-defined conjugated polymers.
