Solvato-Controlled Doping of Conducting Polymers

摘要: Silver(I) is employed to dope poly(3-alkylthiophenes) (P3ATs) and other conjugated polymers. Solutions containing silver(I) salts P3ATs, which usually undergo spontaneous reaction, doping, precipitation, were stabilized using coordinating ligands that modify the reduction potential of Ag(I) species. Upon removal ligand, oxidative doping polymer occurred. Uniform electronically conducting films thus obtained by simultaneous evaporation both solvent Ag(I)-coordinating liganda process termed “solvato-controlled doping”. Doping was observed with a variety consisting relatively electronegative counterions, whereas series possessing increasing head-to-head dyad content showed decreasing tendency Ag(I)-doping due increasingly positive oxidation polymer. Solvato-controlled polyaniline poly(3-methoxythiophene) also described, demonst...
