Outline of Final Research Achievements

Thiophene, a five-membered π-conjugated ring including a sulfur, has been on focus because it is a stable molecule and can be modified easily. Therefore, several thiophene derivatives which exhibited interesting properties, such as semi-conductivity, have been reported.
In this project, we objected to develop efficient methods to construct heteroatom-bridged oligothiophenes. As the platforms for such molecules, we first synthesized multi-brominated bithiophenes and terthiophenes, and we developed efficient methods to synthesize heteroatom-bidged oligothiophenes from these platforms.
