To push forward the structural development and fully explore the potential utility, it is highly desired but challenging to regulate in a controllable manner the structures and properties of MOFs. The authors reported the structural and functional modulation of Cu(II)-tricarboxylate frameworks by employing a strategy of engineering the functionalities and their positions. Two pairs of unsym. biaryl tricarboxylate ligands modified with a Me group and a pyridinic-N atom at distinct positions were logically designed and synthesized, and their corresponding Cu(II)-based MOFs were solvothermally constructed. Diffraction analyses revealed that the variation of functionalities and their positions furnished three different types of topol. structures, which the authors ascribed to the steric effect exerted by the Me group and the chelating effect involving the pyridinic-N atom. Also, gas adsorption studies showed that three of them are potential candidates as solid separation media for acetylene (C2H2) purification, with the separation potential tailorable by altering functionalities and their locations. At 106.7 kPa and 298 K, the C2H2 uptake capacity varies from 64.1 to 132.4 cm3 (STP) g-1, while the adsorption selectivities of C2H2 over its coexisting components of CO2 and CH4 fall at 3.28-4.60 and 14.1-21.9, resp. In the experiment, the researchers used Methyl 5-bromopicolinate(cas: 29682-15-3Safety of Methyl 5-bromopicolinate)
Methyl 5-bromopicolinate(cas: 29682-15-3) belongs to pyridine. Pyridines are often used as catalysts or reagents; particular notice has been paid recently to how pyridine coordinates to metal centers enabling a wide range of valuable reactions. Safety of Methyl 5-bromopicolinate
