Background
Oligothiophenes and polythiophenes (e.g., P3HT) have excellent electronic conductivity and mechanical strength and are widely used in the field of organic electronics. However, thiophene rings usually tend to adopt the s-trans conformation, which has low conductivity, and it has been difficult to stabilize the s-cis conformation, which has higher conductivity. To solve this problem, we developed a technology to fix the thiophene ring in the s-cis conformation by fusing an adamantane skeleton to the oligothiophene. This technology is expected to be applied to a variety of organic electronic materials.
