Both radical-anion and radical- cation-salts derived from C-60-TTF dyads ha
ve been generated and studied in solution, displaying outstanding persisten
ces. The dyad 1c, having the best donor properties, is the only one that fo
rms crystalline radical-cation salts by electrocrystallization which can be
studied. The salt (1c)(x) BF4, in spite of its mixed valence character, do
not has good conducting behaviour.
