Résumé
To gain insight into the host functions of a nanocavity encircled by both polyaromatic panels and heteroatoms, nitrogen-doped polyaromatic capsules were successfully synthesized from metal ions and pyridine-embedded, bent anthracene-based ligands. The new capsules display unique host-guest interactions in the isolated cavities, which are distinct from those of the undoped analogues. Besides the inclusion of Ag

The difference in molecular weight between 2 aN and 2 aCH is <1 %. The optimized structure of 2 aCH provides a spherical cavity with a Pd⋅⋅⋅Pd distance of 1.4 nm and a volume of 550 Å3 (Figure 2 e).
See the Supporting Information. The optimized structures were obtained by DFT calculations (CAM-B3LYP/LanL2DZ,6-31G(d) level of theory). The cavity diameter and volume of the preliminary crystal structure of 2 cN (M=PtII, R=-OCH2CH2OCH3, BF4− counterions) are comparable to those of the optimized structure of 2 aN (Figure 2 d; see Figure S51; CCDC 1995052 contains the supplementary crystallographic data for this paper. These data can be obtained free of charge from The Cambridge Crystallographic Data Centre.).
Ag+ guests adopt a two-coordinate linear geometry with the N-atom of the pyridine spacers of 2 bN and, most probably, the O-atom of solvent (water). In 1H NMR spectra, proton Hf acts as a “reporter” for the successful uptake of guests into the host cavity;

PtII-capsules 2 bN and 2 bCH display no host ability toward C60 even at 80 °C, because of the relatively strong PtII-pyridine bonds;
N-doped capsule 2 bN is an analogue of 2 aN, in which the PdII ions and the short side chains (m=1) are replaced by PtII ions and long side chains (m=3), respectively (Figure 1 b).
2 bN is well soluble in water.
The optimized structures of 2 aN and 2 aCH are rather different in the dihedral angles between the central pyridine or benzene rings and the adjacent anthracene rings (i.e., φ=76.6° for 2 aN and φ=73.1° for 2 aCH). The tightly packed host-guest structure of 2 aN⋅C60 most probably destabilizes the LUMO level of encapsulated C60.

The PdII capsules 2 aN and 2 aCH fully quench the guest fluorescence upon encapsulation because of the heavy-atom effect.
Fluorescence lifetimes of (3)2 within 2 bN and 2 bCH (1.8 and 2.5 ns, respectively) are slightly shorter than that of free 3 (see Figure S39c).
