Facile Catch and Release of Fullerenes Using a Photoresponsive Molecular Tube

Abstract

A novel M<sub>2</sub>L<sub>2</sub> molecular tube capable of binding fullerene C<sub>60</sub> was synthesized from bispyridine ligands with embedded anthracene panels and Ag­(I) hinges. Unlike previous molecular cages and capsules, this open-ended tubular host can accommodate a single molecule of various C<sub>60</sub> derivatives with large substituents. The fullerene guest can then be released by using the ideal, noninvasive external stimulus, light
