Much of the efficient efforts have been largely devoted to enhancing the CO2 binding affinity in MOFs. In this paper, three isoreticular triazolate frameworks with the formula LIFM-1(TAZ).solvents, LIFM-1(MTAZ).solvents and LIFM-1(AmTAZ).solvents (TAZ = 1,2,4-triazole; MTAZ = 3-methyl-1H-1,2,4-triazole; AmTAZ = 3-amino-1H-1,2,4-triazole) have been prepared by using divalent zinc ions with the ligands of TAZ and its amino and methyl substituted derivatives for comparison of their sorption properties. High thermal stability and phase purity of the three MOFs were verified by thermogravimetric an...
