Raman characterization of C60 salts electroformed in aqueous media

The electroreduction of “C60” films in aqueous electrolyte does not lead to alkali metal ion insertion—Evidence for the involvement of adventitious poly-epoxidated C60 (C60On)

“…−1.45 V and −1.35 V vs. SCE. Again, this is in agreement with literature reports [13][14][15][16]20,21] with Szucs suggesting that this is a kinetic effect [13,15].…”

Fullerenes in Liquid Media: An Unsettling Intrusion into the Solution Chemistry

“…412−418 The electrochemical formation of potassium and cesium salts of C 60 in aqueous media is also described. 419 Of special interest is the synthesis of the dimer C 120 O and related compounds. 420,421 Even the fullerene diols 1,2-C 60 (OH) 2 , 1,2-C 70 (OH) 2 , and 5,6-C 70 (OH) 2 are soluble and stable for several days in dilute aqueous acid/dioxane solution, while in dimethylformamide and tetrahydrofurane they decompose.…”

“…Useful procedures for obtaining oxidated and hydroxylated fullerenes were described recently. − The electrochemical formation of potassium and cesium salts of C 60 in aqueous media is also described . Of special interest is the synthesis of the dimer C 120 O and related compounds. , …”

Effect of the electrolyte on the electrochemical behavior of C60 fullerene films in dimethylformamide + water mixtures

“…Later, it turned out, that fullerene films can be reduced, although irreversibly, in aqueous solutions, as well [17][18][19]. Various salt formation [20][21][22][23] and/or hydrogenation and oligomer formation of C 60 was reported [24][25][26]. Recently, we discovered, that in dimethylformamide + water mixtures of proper composition, C 60 could be reduced reversibly, if the solution contained potassium chloride [2].…”
