我们第一次成功地分离出了c -70-苊单加合物的单一纯区域异构体。通过Diels-Alder反应和稳定的二氢并戊烯衍生物2,3-二氯-5,6-二氰-1,4-苯醌（DDQ）和C-70的一锅反应，得到了C-70与并戊烯衍生物的1,9-Diels-Alder单加合物。单个纯区域异构体2b的x射线晶体学研究首次证实了C-70与亚烯之间的连接位置，并显示出独特的柱状堆叠。
We succeeded in the first isolation of a single pure regioisomer of a C-70-acene monoadduct. 1,9-Diels-Alder monoadducts of C-70 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 C-70. The X-ray crystallographic study of a single pure regioisomer 2b confirmed positions of the linkage between C-70 and acenes for the first time, and revealed unique columnar stacks.
