Poly(3-dodecyl-2,2'-bithiophene) (PDBT), Poly(3-dodecylthiophene)(PDT)
, and poly(3,4-dibutoxythiophene)(PDBOT) were chemically prepared and
doped with copper(II) perchlorate. The conductivity, stability and spe
ctral change of the doped polymers during storage in air were compared
. The results suggest that copper(II) perchlorate is an effective oxid
ant.
