Featuring an fcu (face-centered cubic) topology, it consists of 12-connected hexanuclear zirconium oxo-clusters (Zr6O4(OH)4) cross-linked by 2,5-dihydroxyterephthalate linkers. The dual phenolic hydroxyl groups lining the pore channels provide strong hydrogen bonding, dense electrostatic field gradients, and steric aperture contraction tailored for selective gas adsorption and molecular sieving.\u003c\/p\u003e\n\u003cp\u003eFor Gas Absorption \u0026amp; Separation, the key structural and functional features of the UIO-66-(OH)2 are: (1) \u003cstrong\u003eConstricted Sub-Nanometer Pore Geometry\u003c\/strong\u003e: \u003cem\u003eOctahedral Cages\u003c\/em\u003e: Free internal diameter of ~ 9.5–10.5 \u003cspan\u003eÅ \u003c\/span\u003e(constricted from 11 \u003cspan\u003eÅ\u003c\/span\u003e in pristine UiO-66). \u003cem\u003eTetrahedral Cages\u003c\/em\u003e: Free internal diameter of ~ 6.5–7.0 \u003cspan\u003eÅ\u003c\/span\u003e. \u003cem\u003eTriangular Window Apertures:\u003c\/em\u003e\u003cspan class=\"\"\u003e Effective aperture narrowed to \u003c\/span\u003e\u003cspan\u003e\u003cspan class=\"math-inline\"\u003e~ 4.0–4.8 Å\u003c\/span\u003e\u003c\/span\u003e\u003cspan class=\"\"\u003e by the protruding \u003c\/span\u003e\u003cspan class=\"math-inline\"\u003e-OH\u003c\/span\u003e\u003cspan class=\"\"\u003e groups,\u003c\/span\u003e\u003cspan class=\"\"\u003e enhancing size-exclusion sieving for small gas molecules. \u003c\/span\u003e(2) \u003cstrong\u003eDense Hydroxyl Hydrogen-Bonding Environment\u003c\/strong\u003e: The dual phenolic -OH groups provide both hydrogen-bond donor and acceptor sites within the microporous framework, significantly increasing polarizability and dipole-quadrupole interactions with acidic or polar guests.
