The polarographic oxidation potential of TTF is decreased by alkyl- and increased by aryl-substituents.The oxidation potentials of arylated TTF can be correlated with ?(+)-constants (ρ = 0,1).TSF are weaker donors than the respective TTF.Alkyl substitution at TTF causes a bathochromic shift and aryl substitution a hypsochromic shift of the longest wavelength absorption band.In the mono- and dications of TTF a bathochromic shift of this absorption band is observed by alkyl- as well as aryl-substituents which is especially pronounced, when the molecule is planar.
