摘要: Action of acids on TTFs affords cation radicals or/and protonated species, depending conditions and substituents. The reaction TTF derivatives with has been monitored using UV-Vis nmr spectroscopy. Stoichiometric cation-radical salts have synthesized by preparative oxidation phenyliodoso diacetate an acid for comparison. A general scheme the interaction is suggested.
