dc.description.abstractA novel MOF named [Zn-2(L)(DMF)] was synthesized using solvothermal methods from the reaction of the new linker (4,4 ',4 ''-(4,4 ',4 ''-(benzene-1,3,5-triyltris(methylene))tris(3,5-dimethyl-1H-pyrazole-4,1-diyl))tribenzoic acid) and Zn(NO3)(2)<middle dot>6H(2)O. This new MOF was characterized by means of different techniques: powder X-ray diffraction, N-2 adsorption and desorption isotherms, thermogravimetric analysis, and scanning electron microscopy. Furthermore, suitable crystals were obtained, which allowed us to perform the X-Ray structure determination of this MOF. The capability of these new MOF to adsorb CO2 at different temperatures was measured and its isosteric enthalpy of adsorption was calculated. The novel MOF shows an uncommon node composed of a Zn-3(-COO)(6)(DMF)(2), and the asymmetric unit contains one crystallographically independent linker, one DMF molecule, and two Zn atoms. The [Zn-2(L)(DMF)] MOF is a microporous material with high crystallinity and stability up to 250 degrees C. The multiple nitrogenated pyrazole linkers in its framework enhance its CO2 adsorption capabilities. This material exhibits a low CO2 isosteric enthalpy of adsorption (H-ads), comparable to previously reported values for similar nitrogenated materials. All the observed CO2 adsorption capacities were further supported by DFT calculations.
