Influence of alkyl chain on electrochemical and spectroscopic properties of polyselenophenes

During the study, the electronic and optical properties of selenophene compounds were observed to change. The analysis of the selenophene compounds involved the examination of the effect of alkyl chains on polymers obtained during electrochemical polymerization. Four (E,E)-1,4-dialkoxy-2,5-bis[2- (selenophen)-2-yl)ethenyl]benzene derivatives were electrochemically polymerized and characterized. Significant optical differences were observed in the comparison of branched alkyl substituents to linear ones.
