abstract
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 angstrom optimal for the encapsulation of C-60. Remarkably, this organic nanobarrel shows a high affinity for C-60 in solvents in which C-60 is virtually insoluble, providing stable solutions of C-60.
