Monomers and dimers of fullerenes in the radical anion salts with dyes, (astrophloxine+)2(C60˙−)2 and (astrophloxine+)2(C70−)2: suppression of the C60˙− dimerization by π-stacking

Abstract

Radical anion salts (astrophloxine+)2(C60·-)2×C6H4Cl2×C6H14 (1) and (astrophloxine+)2(C70−)2 (2) have been obtained with cationic dye. Singly bonded (C60−)2 dimers are partially formed in 1, whereas singly bonded (C70−)2 dimers are found in 2.
