Abstract
We successfully prepared regioregular hexylthiophene oligomers, dimmer to seximer of hexylthiophene, by using the Suzuki coupling. Introduction of hexyl chain provided excellent solubility to the oligothiophenes; even in seximer, the oligomer was soluble in conventional organic solvents such as toluene and chloroform. Additionally, the oligomer formed thin film with good uniformity by spin-coating from chloroform solution. In this article, we also report optical properties of the oligomer.
