The synthesis of thienylenevinyleneoligomersend-capped with 1,3-dithiole-2-ylidene is described. CV analysis shows that these compounds can be oxidized up to their tetracationic state within a narrow potential window
Thienylenevinyleneoligomers (nTVs) containing up to 10 thiophene rings and bearing solubilizing hexyl groups at the α-position of the end thiophene rings or octyl or dibutyl chains at the 3-position or the 3- and 4-positions of the thiophene rings have been synthesized by a combination of formylation reaction, Wittig−Horner olefination, and McMurry dimerization. Owing to the good solubility imparted
