Synthesis and Physical Characterization of -Alkyl Oligoselenophenes

摘要

alpha-Conjugated oligoselenophenes are characterized by very low solubility in organic solvents. Their higher solubility may be achieved by introducing alkyl side chains into the -positions of selenophene moieties. For the first time, ,-dihexyl sexiselenophene is synthesized according to the conventional approach. Physical and electrochemical studies of ,-dialkyl oligomers are analyzed and compared with corresponding thienyl oligomers.
