Thermal decomposition of inclusion compounds on the base of the metal–organic framework [Zn4(DMF)(ur)2(ndc)4]Part II

Inclusion compounds based on metal–organic frameworks (MOFs) have promising practical applications in gas storage, the separation and fine purification of substances and also in catalysis. These MOFs are crystalline compounds consisting of metal ions coordinated by bridging organic ligands with the formation of porous structures. Here, we study the thermal stability of two inclusion compounds on the base of the new framework: [Zn4(DMF)(ur)2(ndc)4]·5DMF·H2O and [Zn4(DMF)(ur)2(ndc)4]·4ferrocene (ndc2−= 2,6-naphthalenedicarboxylate, ur = hexamethylenetetramine, DMF = N,N′-dimethylformamide, ferrocene = Fe(C5H5)2). The first compound decomposition includes water removal, DMF removal and complex pyrolysis of the empty framework; the kinetics of DMF release is studied. The second compound does not lose the guest molecules before full pyrolysis. The stability of the inclusion compounds with DMF guest molecules on the base of the different host frameworks is considered.
