Conjugated polymers suoh as polyaoetylene (CH)x polyphenylene
(C6H4)x' poly thiophene (C4H2S)x' etc. , which are insulators in
their pristine state, can be brought to the metallic state after
"doping" with ohemioal speoies whioh oan be either eleotron donors
or I aoceptors. . This doping prooess involves a oharge transfer
between the dopant moleoule and the polymer ohain whioh are then
supposed to be spatially olose to each other. It follows that the
meohanism of doping must be oonsidered as an aotual interoalation
process, which will greatly affeot the struotural oharacteristios
of the starting material, as well as its morphology, as has been
observed during the 2 intercalation of graphite and layered
compounds . In parallel with these modifioations, the band
struoture of the system changes yielding a new set of eleotronio
properties. It is evident therefore that the struotural and
eleotronio properties are intimately related, and must be studied
simultaneously in the same system to give reliable information. A
great number of studies have been devoted to the structural and
electronic properties of conjugated polymers after a chemical or 2
electrochemical doping process . Most of these concern the
properties of the system for a given dopant concentration. With
this approach a universal pioture of the polymer/dopant system is
very diffioult to obtain, as a comparison between different
experiments is very hazardous. On the other hand, only a small
number of measurements have been performed during the continuous
electroohemioal doping of various polymers.
