Novel Fused D−A Dyad and A−D−A Triad Incorporating Tetrathiafulvalene and <i>p</i>-Benzoquinone
compounds of the cation radical and anionradical obtained upon (electro)chemical oxidation and reduction, respectively, was monitored by optical and ESR spectroscopies. The anionradical Q−TTF−Q-• triad was demonstrated to be a class II mixed-valence system with the existence of a temperature-dependent intramolecular electron transfer. The crystallographic tendency of these fused systems to overlap in
