{"product_id":"cgasmofzif8","title":"ZIF-8 Metal Organic Frameworks (MOFs) Powder for Gas Absorption and Separation, CGASMOFZIF8","description":"\u003cp\u003eZIF-8 (Zeolitic Imidazolate Framework-8, Zn(MeIM)2, where MeIM = 2-methylimidazolate) is a sodalite-topology metal-organic framework built from tetrahedrally coordinated Zn2+ nodes linked by methylimidazolate rings. The Zn–N–C bond angle (~ 145\u003cspan\u003e°\u003c\/span\u003e) mimics the Si–O–Si bridging angle in classical aluminosilicate zeolites, combining the high chemical\/thermal stability of zeolites with the tunable porosity of MOFs.\u003c\/p\u003e\n\u003cp\u003eThe key structural features of theZIF-8 are: (1) \u003cstrong\u003eSodalite (SOD) Topology\u003c\/strong\u003e: \u003cem\u003ePore Cavity\u003c\/em\u003e: Large spherical central cage with a diameter of ~ 11.6 Å. P\u003cem\u003eore Aperture\u003c\/em\u003e: Narrow 6-membered ring windows with a nominal crystallographic diameter of ~ 3.4 \u003cspan\u003eÅ\u003c\/span\u003e. (2) \u003cstrong\u003e\"Gate-Opening\" Framework Flexibility\u003c\/strong\u003e: The 2-methylimidazolate linkers undergo a coordinated rotational \"swinging\" motion (gate opening) under guest molecule pressure. This increases the effective accessible window diameter from its nominal ~3.4 \u003cspan\u003eÅ\u003c\/span\u003e up to ~ 4.0–4.2\u003cspan\u003eÅ\u003c\/span\u003e, enabling diffusion of molecules nominally larger than the static aperture.
