Abstract

Abstract The substituent effect of the dihydro [60] fullerenyl group and its hydrophobic parameters have been evaluated quantitatively. The substituent constant has been determined from the pK value of a fullerene-based, para-substituted benzoic acid 1 in 80% dioxane/water (v/v) by NMR spectroscopy. The resulting Hammett σ value of 0.06, consistent with a small electron-withdrawing effect of C 60, is a consequence of the fact that only ...
