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

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.
