4-Ferrocenylphenyl-Substituted Tritylium Dyes with Open and Interlinked C+Ar2 Entities: Redox Behavior, Electrochromism, and a Quantitative Study of the Dimerization of Their Neutral Radicals

We report on seven 4-ferrocenylphenyl-substituted tritylium dyes Fc-C6H4-C+Ar2 with either unlinked or interlinked aryl residues Ar, including congeners with six-membered (thio)xanthylium and seven...
