Chemically doped materials

Although it was initially believed that polyacetylene was unstable in contact with water under all conditions, it has been successfully chemically doped in aqueous solutions with no apparent degradation of the material [82] and its electrochemistry has also been investigated [135-137] from which it is clear that no degradation occurs in concentrated aqueous electrolytes. Reaction with water can occur under some circumstances however giving rise to sp3 carbons and carbonyl-type structures [129, 138-141],... 

Figure 10 The variation of Tc with bond length is shown in (a) and in (b) is a schematic representation of the motion of the atoms (i.e., of the charge transfer) as the chemical doping at the Cul site proceeds. Note that this picture applies as well when the oxygen content in the material changes.
