Electrocrystallization of C 60 and organic dye cations produces crystals of C 60 anion radical salts stabilized by these cations. The ESR spectra of these salts showed typical broad signal which can be ascribed to C 60 superimposed by small sharp signals. The conducting properties of some salts of C 60 anion radicals stabilized by bulky organic dye cation, e.g., Methyl Green salts of C 60 display rather stable conducting behavior even under atmosphere: semiconducting until ca. 150 K, then metallic to ca. 100 K, and finally showing a sharp transition to insulator around this temperature.
