Synthesis and characterization of a novel [60]fullerene-tetrathiafulvalenedyad

A novel [60] fullerene-tetrathiafulvalene dyad (4) was prepared by Bingel r e action of C-60 and 2,3-bis{[(methoxycarbonyl)-acetoxy]ethylthio} -6,7-bis (hexadecylthio)tetrathiafulvalene (3) in the presence of iodine and diazabi cyclo[5.4.0]undec-7-ene, and characterized by spectroscopy and electrochemi cal study. It was found that the paramagnetic signals (g = 2.0027, line wid th 0.1540 mT) were shown in the EPR spectrum of the derivative at room temp erature without photoinduction, indicating efficient intramolecular electro n transfer between both electroactive moieties.
