In addition to positively impacting issues of dedoping of pH and thermally sensitive polymers such as polyaniline, self-doped forms enable the combination of p- and n-type conducting polymers without their spontaneous discharging by the concerted recombination of carriers and counterions. This has resulted in the formation of conjugated polymer p/n junctions, not possible with standard conjugated polymers. ... 

Raman spectroscopy of conducting polymers has mainly treated the structures of intact polymers (geometry of polymer chains, conjugation length, force field, etc.) [13-15]. Although the Raman spectra of doped polymers have been reported [13-15], the observed Raman bands have not been correlated to the types of self-... 

Havinga et al. prepared 3 -propylpotassiumsulfo-nate-2,2 -5, 2"-terthienyl [21], This type of compound is useful as a starting material for self-doped water-soluble conductive polymers. 

The polymer is stable at temperatures up to 380 °C. Optically clear, self-supporting layers having a modulus of elasticity of 1.3 GPa can be prepared from a solution. Layers of the polymer adhere very well to metals, in particular to gold. By means of oxidation agents, PPSA can be doped to form ap-type material. Doping of a self-supporting layer of PPSA with SbCls results in an electric conductivity of 0.18 S cm , while doping with FeCls leads to a conductivity of 0.8 S cm ...
