Summary: Two novel conjugated isomeric hexathiophenes 6T1 and 6T2 bearing 5‐methyl‐2‐thienyl substituents have been synthesized by Suzuki coupling and oxidative dimerization method. These isomers were characterized by 1 H NMR, 13 C NMR, elemental and mass analysis. The two hexamers show good solubility in common solvents and show almost identical UV‐vis absorption spectra in solution with a maximum cantered at 387 nm. These materials bearing thienyl substituents in the sidechain are anticipated to provide better charge transport in devices and hold promise for use in organic field effect transistors.
