A porous metal-organic framework, Co(II)(4)(micro-OH(2))(4)(MTB)(2) x (H(2)O)(4) x 13nDMF x 11nH(2)O (SNU-15), has been prepared; the X-ray crystal structure reveals a CaF(2)-like structure that generates 3D channels and the desolvated solid Co(II)(4) (micro-OH(2))(4)(MTB)(2) (SNU-15') exhibits selective gas sorption properties for H(2) and O(2) gases over N(2) at 77 K, with exceptionally high O(2) density, as well as for CO(2) over CH(4) at 195 and 273 K, suggesting its potential application in gas separation processes.
已制备出一种多孔金属有机骨架材料[Co(II)₄(μ-OH₂)₄(MTB)₂·(H₂O)₄]ₙ·13nDMF·11nH₂O(SNU-15);X射线晶体结构显示其具有类似CaF₂的结构,能形成三维通道,去溶剂化后的固体[Co(II)₄(μ-OH₂)₄(MTB)₂]ₙ(SNU-15')在77 K下对H₂和O₂气体相对于N₂表现出选择性气体吸附特性,具有极高的O₂密度,并且在195 K和273 K下对CO₂相对于CH₄也有选择性吸附,这表明其在气体分离过程中具有潜在应用价值。
