Solitonic States in Organic Conducting Polymers

Document Type : Research Paper

Abstract

In a typical solitonic distribution, the soliton density is distributed over the entire molecule
and the present work shows how its density can be decomposed into solitonic and antisolitonic
components. It is found that there exists a unique electron as soliton over the anionic
nanoconductor, while there are many other solitons and antisolitons. The solitonic states are further
decomposed to the canonical molecule orbitals including the highest occupied molecular orbital
(HOMO) and lowest unoccupied molecular orbital (LUMO), and it is concluded that LUMO is not
necessarily occupied by one electron in the studied molecules. Also, analogous electrons were
found to be responsible for spin separation which is revealed from distinct contributions in different
molecular regions of the nanoconductor.
