The four\u2010jaw C4A unit tends to follow the face\u2010directed self\u2010assembly law with the planar triangular building blocks such as tris(4\u2010aminophenyl)amine (TAPA) or 1,3,5\u2010tris(4\u2010aminophenyl)benzene (TAPB) to generate a predictable cage with a stoichiometry of [6+8]. The formation of the large cages is confirmed through their relative molecular mass measured using MALDI\u2010TOF\/TOF spectra. The protonated molecular ion peaks of C4A\u2010TAPA and C4A\u2010TAPB were observed at m\/z 5109.0 (calculated for C<jats:sub>336<\/jats:sub>H<jats:sub>240<\/jats:sub>O<jats:sub>24<\/jats:sub>N<jats:sub>32<\/jats:sub>: m\/z 5109.7) and m\/z 5594.2 (calculated for C<jats:sub>384<\/jats:sub>H<jats:sub>264<\/jats:sub>O<jats:sub>24<\/jats:sub>N<jats:sub>24<\/jats:sub>: m\/z 5598.4).
