A novel copper-based MOF material: Synthesis, characterization and adsorption studies

A Microporous Copper Metal–Organic Framework with High H2 and CO2 Adsorption Capacity at Ambient Pressure

“…The hysteretic adsorption behavior in that pressure range indicates a plausible structural transformation of the non-rigid material. [20,21,25,29] This transition appears also in the N 2 (77 K) isotherm, however it is reversible and smeared-out over a wider relative pressure range from 0.005-0.1. CO 2 adsorption on 1 d was studied at 273 K, 298 K, and 323 K and used to calculate the isosteric heat of adsorption ( Figures S8 and S9).…”

“…The ligand Me-4py-trz-ia 2À (Figure 1 a), which can be obtained from cheap starting materials by a three-step synthesis in good yield, combines carboxylate, triazole, and pyridine functions and is adopted from a recently presented series of linkers, [18] for which up to now only a few coordination polymers are known. [19][20][21][22] Single crystals of 1 that are suitable for X-ray crystal structure analysis were prepared by diffusion of copper sulfate and H 2 (Me-4py-trz-ia). Larger quantities of microcrystalline 1 are obtained not only by solvothermal synthesis, but also in multigram scale by simple reflux of the starting materials in water/acetonitrile (see Supporting Information).…”

Luminescent Sensing of Volatile Organic Compounds Using a Zn-based Coordination Polymer with Tunable Morphology

“…The (2) content of porous accessible for the nitrogen molecules and the absorption capacity in 1 are slightly higher than those of 2. This can be explain by the assumption that the pores of 2 preparing by room temperature stirring route in DMF, still contain residues of molecules solvent an possibly nonreacted starting material, which cannot be emptied during activation at 90 °C in vacuum, as previously reported Staudt et al is also possible and could be responsible of the low absorption capacity in comparison of 1 [41]. Table 2 shows the specific surface areas calculated using the BET equation and the pore volume obtained from the amount of nitrogen adsorbed of 1 and 2.…”

Metal–organic frameworks in Germany: From synthesis to function

“…Hence, their coordination chemistry formally resembles that of neutral 1,2-diazole ligands and shall not be reviewed here any further. Illustrative examples of frameworks derived from this approach include bitopic linkers such as 4-(4H-1,2,4-triazol-4-yl)benzoic acid [83,84,85] or polytopic triazole linkers containing an adamantyl backbone [86,87].…”
