Nanometer-Scale Fullerene-Type Conjugated Covalent Cages Based on Triazine: Design, Doping with Li <sup>+</sup> , and H <sub>2</sub> /CO <sub>2</sub> Adsorption
Spherical and hollow molecular cages based on planar triazine (C<sub>3</sub>N<sub>3</sub>) hubs and aromatic phenylene connectors have been developed. The cages exhibit topologies akin to C<sub>20</sub>, C<sub>60</sub>, and C<sub>70</sub> fullerenes with diameters that range from 2.3 to 4.9 nm. Apertures into the cage interiors are tuned by varying the aromatic connectors situated between the C<sub>3</sub>N<sub>3</sub>-units. The stabilities of the C<sub>3</sub>N<sub>3</sub> cages increase with size owing to reduced bending strain of planar nodes and connectors that make up the spherical aromatic networks. Doping of the cages with Li<sup>+</sup> reveals the capacity of the cages for significant adsorption of gaseous H<sub>2</sub> and CO<sub>2</sub>. The design of graphene-like spherical cages is also discussed.
