Add-Ons
HKUST-1 (Hong Kong University of Science and Technology-1, also known as Cu-BTC or Cu3(BTC)2, where BTC = benzene-1,3,5-tricarboxylate is a 3D porous metal-organic framework built from dicopper "paddlewheel" secondary building units (Cu2(COO)4) connected by planar trimesate linkers.
The key structural features of the HKUST-1 MOF are: (1) Open Metal Sites (Lewis Acidic Cu2+): Upon thermal activation, coordinated axial solvent molecules (water or ethanol) are removed from the Cu2 paddlewheels, exposing coordinatively unsaturated Cu2+ Lewis acid sites. These open metal sites strongly polarize guest molecules with dipoles or quadrupoles. (2) Hierarchical Bimodal Pore Architecture: Large Pores: ~ 11–13.5 Å cubic cages with ~ 9 Å window apertures. Small Tetrahedral Pores: ~ 5–6 Å cages with ~3.5 Å triangular windows. (3) Textural Properties: BET Surface Area: Typically 1500–2100 m2/g (crystallinity and activation-dependent). Total Pore Volume: ~0.65–0.85 cm^3. Bulk Density: Relatively low crystal density (~ 0.88 g/cm3).
