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
