THE POLY-POLYACENE FAMILY OF MULTI-PHASE PI-NETWORK POLYMERS IN A VALENCE-BOND PICTURE Academic Article uri icon

abstract

  • A family of long polymer strips are argued to exhibit distinct phases each with a different long-range ordering in electronic structure. Degenerate ground-state phases necessarily occur (due to symmetry) for odd width strips, and may also occur for even width strips. A new type of solitonic excitation is indicated; it may be viewed as consisting of a group of bound solitons that cannot mutually annihilate (i.e. there are no antisolitons in the group). Valence-bond and band-theoretic molecular-orbital views are compared. 1985.
