AbstractThe syntheses and the electronic properties of oligo(2,7‐biphenylenylene‐(E)‐vinylene)s are reported. According to our spectral analysis, a limit of 2.5 ev for the peak band‐gap of poly(2,7‐biphenylenylene‐(E)‐vinylene)s is estimated. In addition, we discovered that oligo(2,7‐biphenylenylene‐(E)‐vinylene)s are amphoteric and can be either oxidized or reduced electrochemically.
