Organic cages have gained increasing attention in recent years as molecular hosts and porous materials. Among these, barrel-shaped cages or molecular nanobarrels are promising systems to encapsulate large hosts as they possess windows of the same size as their internal cavity. However, these systems have received little attention and remain practically unexplored despite their potential. Herein, we report the design and synthesis of a new trigonal prismatic organic nanobarrel with two large triangular windows with a diameter of 12.7 Å optimal for the encapsulation of C . Remarkably, this organic nanobarrel shows a high affinity for C in solvents in which C is virtually insoluble, providing stable solutions of C .
近年来,作为分子主体和多孔材料,有机笼受到了越来越多的关注。在这些有机笼中,桶状笼或分子纳米桶是一种很有前途的系统,因为它们具有与内部空腔相同大小的窗口,可以封装大的客体。然而,尽管这些系统具有很大的潜力,但它们受到的关注很少,几乎没有得到实际探索。在此,我们报告了一种新型三角棱柱有机纳米桶的设计和合成,该纳米桶具有两个大的三角形窗口,直径为 12.7 Å,非常适合封装 C 。值得注意的是,这种有机纳米桶对 C 在溶剂中的亲和力很高,而 C 在这些溶剂中几乎不溶,从而提供了 C 的稳定溶液。
