Add-Ons
MIL-68(Al) (Al(OH)(BDC), where BDC = 1,4-benzenedicarboxylate}) is an aluminum-based metal-organic framework containing infinite 1D chains of corner-sharing AlO4(OH)2 octahedra bridged by terephthalate linkers. While sharing the identical chemical composition with the widely studied MIL-53(Al), MIL-68(Al) is a rigid structural polymorph with a Kagome-like network that features dual 1D straight channels and does not undergo framework breathing transitions.
The critical structural and functional features of the MIL-68(Al) are shown below: (1) Dual 1D Channel System (Kagome Lattice): Large Hexagonal Channels: Internal diameter of ~16.0–17.0 Å (accessible window ~ 14.5 Å), allowing rapid diffusion of larger gas guests and organic vapors. Small Triangular Channels: Internal diameter of ~ 6.0–6.5 Å, offering size-selective micropores with strong confinement effects for small gas molecules. (2) Rigid Framework Topology: Unlike MIL-53(Al) (which flexes between narrow-pore and large-pore forms under pressure/temperature), the connecting mode in MIL-68(Al) locks the framework in a rigid, permanently open state across all pressures and hydration levels. (3) Chemical, Hydrothermal & Thermal Stability: The Al–O coordination chains provide exceptional stability in water, humidity, and mild acidic media, with thermal stability extending up to ~ 450–500°C in air/inert atmospheres.
