“…In the past few years, our interest in the field has led to several new Metal-Organic Frameworks, as well as a number of organic linkers that can be used in MOF design [24][25][26][27][28][29][30][31][32][33][34][35][36]. With the goal of obtaining novel MOFs with permanent porosity which have the potential to be used for gas storage, in this work we synthesized and characterized three new Metal-Organic Frameworks, obtained using Zn (II) and Cd (II) as metal sources and 2,4,6-tris(4carboxyphenyl)-1,3,5-trimethylbenzene (mesitylene tribenzoic acid-H 3 MTB) an organic linker which to this day, has only seen limited use in MOF design.…”

Three new Metal-Organic Frameworks, containing mesitylene tribenzoic acid as a linker and zinc (1) or cadmium as metals (2,3), were synthesized through solvothermal reactions, using DMF/ethanol/water as solvents, at temperatures of 80 °C (structures 1 and 3) and 120 °C (structure 2). Following single-crystal X-ray diffraction, it was found that 1 and 3 crystallize in the P21/c and C2/c space groups and form 2D networks, while 2 crystallizes in the Fdd2 space group, forming a 3D network. All three frameworks, upon heating, were found to be stable up to 350 °C. N2 sorption isotherms revealed that 1 displays a BET area of 906 m2/g. Moreover, the porosity of this framework is still present after five cycles of sorption/desorption, with a reduction of 14% of the BET area, down to 784 m2/g, after the fifth cycle. The CO2 loading capacity of 1 was found to be 2.9 mmol/g at 0 °C.
