Polaron States of 3,4-Ethylenedioxythiophene Oligomers
The electronic and spatial structure of 3,4-ethylenedioxythiophene oligomer containing 12 units (E12) in 0, +1, +2, +3, and +4 charge states has been calculated by the method of density functional theory (B3LYP 6-31 G**). It is shown that electron conductivity in the oxidized oligomer E124+ is provided by two bipolarons at the ends of the chain.
