Synthesis and Characterization of Oligo(2,7-biphenylenylene-(E)-vinylene)s: Conjugated Oligomers Containing Antiaromatic 12-π Electron Units

The syntheses and the electionic 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.

Synthesis and characterization of oligo(2,7-biphenylenylene-(E)-vinylene)s

The syntheses, spectral behavior, and electrochemical properties of novel oligo(2,7-biphenylenylene-(E)-vinylene)s (OBPV's) 1 to 3 have been reported. On the basis of the spectral analysis of OBPV's, a band gap of 2.5 ev for poly(2,7-biphenylenylene-(E)-vinylene) was estimated.
