Bottom-up approaches to form superatom-assembled 2D few-layered borophanes and carborophanes and 3D α-B12, γ-B28, and B4C based on icosahedral B12 and CB11 building blocks.

Bottom-up approaches to form the superatom-assembled 2D few-layered α-rhombohedral borophanes (B12)nH6 (α-1–5) in (111) direction (a) and (B12)nH2  (α-6–10) in (001) direction (b), 2D γ-orthorhombic borophanes (B12-B2)nH8 (γ-1–5) in (001) direction (c), and (CB11-CBC)nH8 (σ-1–5) in (010) direction (d) (n = 1–5) and 3D crystals α-B12, γ-B28, and CB11-CBC using the aromatic icosahedral B12H122– and CB11H12– as precursors at GGA-PBE level via partial or complete dehydrogenations, with the B-B dumbells in γ-1–5 and C-B-C chains in σ-1–5 serving as interstitial structural units to help stabilize the icosahedral B12 and CB11 cages.
