ligand decorated with amino and sulfoxide groups, 5′,5′′′′-sulfonylbis (2′-amino-[1,1′:3′,1′′-terphenyl]-4,4′′-dicarboxylic acid) (H4L), was employed to construct a new microporous iron-organic framework (Fe-MOF) with the formula [(Fe3O)(L)1.5(H2O)3]n. This MOF can serve as a parent structure to obtain the isostructural Cr-MOF by solvent-assisted metal metathesis. Furthermore, the gas adsorption and separation
从 C 2 H 2中去除 CO 2或 C 2 H 4仍然是一项具有挑战性的任务,因为它们具有相似的物理化学性质。在这里,用氨基和亚砜基团修饰的双功能配体,5',5''''-磺酰基双(2'-氨基-[1,1':3',1''-三联苯]-4,4''-二羧酸) (H 4 L), 用于构建新的微孔铁-有机骨架(Fe-MOF),分子式为[(Fe 3 O)(L) 1.5 (H 2 O) 3 ] n. 这种MOF可以作为母体结构,通过溶剂辅助金属复分解获得同构Cr-MOF。此外,系统地研究了这两种 MOF 的气体吸附和分离性能。与Fe-MOF相比,Cr-MOF显示出适度更高的CO 2、C 2 H 2和C 2 H 4吸收能力。另外,Cr-MOF可以选择性地吸附C 2 H 2而不是CO 2和C 2 H 4。对 C 2 H 2 /C 2 H 4和 C 2 H 2的分离电位/CO 2通过混合物吸附平衡的 IAST 计算进一步确定。在

A vesicle incorporate a transmembrane protein, the vesicle forming material including a mixture of poly(ethylene glycol)-block-poly(propylene glycol)-block-poly(ethylene glycol) and polyetheramine. The vesicle can generally withstand elevated temperature without substantial shrinkage of the diameter, which in turn results in maintenance of the water permeability virtually unaffected. Pluronic based vesicles have a large content of amino groups available on the surface illustrated by the larger zeta potential values available for crosslinking in the polyamide layer by chemical reaction with trimesoyl chloride (TMC).
