| Outline of Final Research Achievements |
Direct arylation polymerization has recently been recognized as a promising tool for the practical synthesis of π-conjugated polymers. While the reaction is an atom- and step-economical process, it requires the elevated temperature because of cleavage of sp2 C-H bonds efficiently. The harsh conditions would prevent the controlled growth of the polymer chain. To implement the polymerization under mild conditions, we have conducted molecular design of the monomers and introduction of co-catalyst for effective C-H functionalization. After exploring the appropriate reaction conditions, the reactions produced the corresponding π-conjugated polymers at room temperature.
