The first self-assembly of a C60 
-extended tetrathiafulvalene (exTTF) dyad on a gold surface is reported. Fourfullerene derivatives, two of them containing p-quinonoid -extended tetrathiafulvalenes (exTTFs), have been synthesized,and their solution electrochemistry has been investigated by means of cyclic voltammetry. Fullerene-containing SAMsof thioctic acid derivatives 3 and 6 have also been investigated by cyclic voltammetry. The cyclic voltammogramsof both compounds exhibit three reversible reduction waves, and for compound 6, one irreversible oxidation processcorresponding to the oxidation of the exTTF subunit is observed. Stable self-assembled monolayers (SAMs) offullerene derivative 3 were formed on gold surfaces, whereas dyad 6 does not present a very clear electrochemicalresponse, most probably as a result of structural rearrangements on the monolayer or charge transfer between the C60and exTTF moieties.
