Add-Ons
MIL-68(Fe) (Fe(OH)(BDC), where BDC = 1,4-benzenedicarboxylate) is an iron-based, rigid metal-organic framework featuring infinite 1D chains of corner-sharing FeO4(OH)2 octahedra bridged by terephthalate linkers. Unlike its flexible, breathing polymorph MIL-53(Fe), MIL-68(Fe) crystallizes in a Kagome-like lattice topology containing permanent dual 1D channels that offer high structural rigidity, earth-abundant non-toxic iron nodes, and redox-active metal sites.
The critical structural and functional features of the MIL-68(Fe) 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(Fe) (which flexes between narrow-pore and large-pore forms under pressure/temperature), the connecting mode in MIL-68(Fe) locks the framework in a rigid, permanently open state across all pressures and hydration levels. (3) Redox-Active & Lewis Acidic Iron Sites: Trivalent iron centers Fe^{3+} along the infinite octahedral chains act as Lewis acid sites and participate in reversible redox processes Fe^{3+}/Fe^{2+}, enhancing affinity for polarizable guest molecules.
