The carbon cage of these C-60 derivatives is decorated with one or two dodecyl or triethylene glycol tails, through the appropriately modified ortho-xyleno bridge, by utilizing the Diels-Alder reaction of C-60 with the corresponding especially designed, novel, in situ-prepared ortho-quinodimethanes. Two different synthetic approaches were de-signed and followed for the preparation of these adducts. All fullerene derivatives were characterized via H-1-and C-13-NMR, matrix-assisted laser desorption-ionization mass spectrometry, as well as, by FT-IR and UV-Vis spectroscopies and cyclic voltammetry. All adducts exert very high solubility in common organic solvents like chloroform, tetrahydrofuran, and toluene." }
