Three oligothiophenes containing alkoxy groups were synthesized, and their optical, electrochemical, and electrical properties were investigated. The oligothiophenes were soluble in common organic solvents owing to the presence of flexible alkyl chains in their alkoxy groups. The introduction of alk...
