摘　　要：The controlled self-assembly of discrete metal-organic nanocapsules(MONCs),and metal-organic frameworks(MOFs)based on the MONCs are achieved.Specifically,the solvothermal reaction of nickel nitrate hexahydrate and C-methylpyrogallol[4]arene in mixed DMF/MeOH solution leads to the unexpected form of discrete nickel-seamed hexameric pyrogallol[4]arene MONCs,and MONC-based three-dimensional(3D)MOF.Notably,the latter MOF is constructed from the aforementioned nickelseamed MONC building blocks and formate linkers in-situ generated from the hydrolysis of DMF solve nt.Interestingly,introducing pyridine and formic acid in the reaction conditions leads to the controlled assemblies of the discrete MONC and MONC-based 3D MOF structures.Moreover,the variabletemperature magnetic susceptibilities of both the abovementioned compounds have been investigated,indicating typical antiferromagnetic interactions between the metal centers.
