Abstract
Storage and chemical stability of TCNQ anion radical salts with polycations containing sulfur atoms in the main chain was investigated as a function of time and solvent used for their synthesis. The UV and visible light absorption spectra of solution have evidenced that the storage of these polymeric salts at room temperature results in the appearance of a new absorption band asscribed to α,α-dicyano-p-toluoylcyanide anion. It was found that the ageing reaction depends on the residual solvent as well as on the method of synthesis of these complex salts.
