Targeted design of three new amide-functionalized metal-organic frameworks for enhancement of the capability of epoxide ring-opening reaction catalysis

Synthesis of MOFs compound with particular functionalized ligand is not always successful, and sometimes it cannot be synthesized easily and directly even using multiple methods. Hence, this limitation can be overcome by applying a post synthesis way which is swapping functional groups without changing the whole backbone of pillar ligand. Solvent-assisted functionality exchange (SAFE) is a post synthesis method which has been assisted to confront this challenge by replacing functional groups together. In this investigation, we tried to improved properties of the MOFs compound and increase their catalytic efficiency by importing a new functional group into their structures. N1, N3-di(pyridine-4-yl) malonamide linker (S) is one the pillar ligand which is not easily entering to the structure in order to synthesis MOFs compound. Therefore, to solve this issue , amide functionalized benzene-cored ligand derivatives were designed as linkers for manufacture of new 3D structures of [Co(oba)(bpta)]•(DMF)2 TMU-50, [Co2(oba)2(bpfn)]•(DMF)2.5 TMU-51 and one novel 2D [Co(oba)(bpfb)]•(DMF)2 TMU-49 , layered of compound via hydrothermal reaction. Also, their ability as catalysts was figured out in the methanolysis reaction of epoxides
