Novel [60]fullerene-TTF cyclohexene fused polyadducts: unprecedented tri-and tetra-Diels-Alder adducts of dimethylidene[2H]tetrathiafulvalenes with C_60

摘要

The title compounds, which are formed in very low yields of treating 2,3-bis(bromomethyl)tetrathiafulvalenes with naked iodide in the presence of C_60, can be obtained in much higher yields by successive similar treatments of the major adducts produoced at each step. The electrochemical properties of the unprecedented tri-and tetra-TTF/C_60 assemblies are also presented.
