A series of α,ω-aldehyde-capped thiophene oligomers with two, four and six thiophene units have been prepared via a convenient, three-step synthesis in good yields. The UV-vis spectral data show that the π-conjugation length in the tetramer is longer than those in the hexamer and in the dimer in various solvents.
