The syntheses and structural properties of novel triscyclophanes that bear the rigid, bowl‐shaped tribenzotriquinacene (TBTQ) core are reported. Condensation of the 2,3,6,7,10,11‐hexakis(chloromethyl) derivative with catechols and 1,2‐benzenedithiol gives rise to elongation of the three indane wings (intra‐wing extension), whereas incorporation of resorcinol, hydroquinone, and 1,3‐ and 1,4‐benzenedithiol units occurs by bridging the 3D bays of the TBTQ framework (inter‐wing extension), yielding TBTQ‐based cavitands. Constitutional and conformational details were studied by X‐ray diffraction, VT‐NMR spectroscopy, and molecular modeling. The bay‐bridged TBTQ‐based triscyclophanes bearing 1,3‐dioxy‐ and 1,3‐dithiophenylene units adopt globular and cone‐likeC3‐symmetrical shapes, respectively, with limited conformational flexibility. Bay‐bridging by 1,4‐dioxy‐ and 1,4‐dithiophenylene units generates a more complanate coverage of the bowl face with even less conformational flexibility.
