Abstract
Normal 0 The C 60 fullerene/tetracene adduct was synthesized and studied by electronic absorption spectroscopy and FT-IR spectroscopy. Essentially the monoadduct was obtained as suggested by the spectroscopic analysis and by the thermogravimetric analysis (TGA). The stability and the retro Diels-Alder reaction of the C 60 /tetracene adduct was studied by TGA, differential thermogravimetric analysis (DTG) and by differential scanning calorimetry (DSC). It was found that the adduct is stable above 300°C and decomposes at 323°- 390°C according to the DSC analysis. The decomposition involves the release of tetracene and the restoration of C 60 in high yields. However, part of the C 60 is lost as amorphous carbon in the retro Diels-Alder reaction.
