Résumé
A large cationic triangular metallo-prism, [Ru6(<i>p</i>-Pr<sup>i</sup>C<sub>6</sub>H<sub>4</sub>Me)<sub>6</sub> (tpt)<sub>2</sub> (dhbq)<sub>3</sub>]<sup>6+</sup> (<b>1</b>)<sup>6+</sup>, incorporating p-cymene ruthenium building blocks, bridged by 2,5-dihydroxy-1,4-benzoquinonato (dhbq) ligands, and connected by two 2,4,6-tri(pyridin-4-yl)-1,3,5-triazine (tpt) subunits, allows the permanent encapsulation of the triphenylene derivatives hexahydroxytriphenylene, C<sub>18</sub>H<sub>6</sub> (OH)<sub>6</sub> and hexamethoxytriphenylene, C<sub>18</sub>H<sub>6</sub> (OMe)<sub>6</sub>. These two cationic carceplex systems [C<sub>18</sub>H<sub>6</sub> (OH)<sub>6</sub>⊂<b>1</b>]<sup>6+</sup> and [C<sub>18</sub>H<sub>6</sub> (OMe)<sub>6</sub>⊂<b>1</b>]<sup>6+</sup> have been isolated as their triflate salts. The molecular structure of these systems has been established by one-dimensional <sup>1</sup>H ROESY NMR experiments as well as by the single-crystal structure analysis of [C<sub>18</sub>H<sub>6</sub> (OMe)<sub>6</sub>⊂<b>1</b>][O<sub>3</sub>SCF<sub>3</sub>]<sub>6</sub>.
