Synthesis, optical, and electrochemical properties of conjugated oligomers derived from 4-bromo-4′-(n-butyl)-2,2′-biphenyl

The synthesis, optical, and electrochemical properties of semi-conducting co-oligomers of biphenyl/oligothiophenes and homo-oligophenylenes derived from a precursor 4-bromo-4′-(n-butyl)-2,2′-biphenyl, which was synthesized by a direct alkylation from 4,4′-dibromo-2,2′-biphenyl using n-butyl lithium, are reported.
