Abstract
UV-Vis spectra of fullerene C60 in various mixtures of polar N-methyl-2-pyrrolidone (NMP), ϵ = 32, and low-polar toluene, ϵ = 2.4, are analyzed. A sharp solvatochromic effect is observed when toluene is added to C60/NMP. The comparison with the effect of water addition, ϵ = 80, to C60/NMP is given.
