| Outline of Final Research Achievements |
Diels-Alder reaction of fullerenes with acenes is among the most studied addition reactions. Although [60]fullerene-acene reactions using scenes have been reported, there are only a few examples of the reaction of acenes with C70. We succeeded in the first isolation of a single pure regioisomer of a C70-acene monoadduct. 1,9-Diels-Alder monoadducts of C70 with pentacene derivatives were obtained by not only the Diels-Alder reaction but also a one-pot reaction using stable dihydropentacene derivatives, 2,3-dichloro-5,6-dicyano-1,4-benzoquinone (DDQ), and C70. The X-ray crystallographic study of a single pure regioisomer confirmed positions of the linkage between C70 and acenes for the first time, and revealed unique columnar stacks.
