Likewise, 2,5-bis pentafluorophenylethynyl thiophene 2 was prepared by the coupling of 2,5-diiodothiophene with pentafluorophenylacetylene. Frequency calculations confirm the assignments of the compounds' IR and Raman spectra. The short singlet lifetimes and modest fluorescence quantum yields ca.

The short singlet lifetimes and modest fluorescence quantum yields ca. DFT calculations show that the all-planar form of the compounds is the lowest in energy, although rotation of the phenyl groups about the C[triple bond, length as m-dash]C bond is facile and TD-DFT calculations suggest that, similar to 1,4-bis phenylethynyl benzene analogues, the absorption spectra in solution arise from a variety of rotational conformations.
