Highlights

  • The host and apohost frameworks of two MOFs were used for preparation of nano ZnO.

  • The morphology of initial precursors has direct influence on morphology of nano ZnO.

  • Types of the linker ligands and solvent molecules affect on formation of nano ZnO.

  • In one case, solvent molecules and in another linker ligand is the effective factor.

  • The role of ligands and guest molecules is similar to the polymeric stabilizers.

Abstract

The host and the apohost frameworks of Zn2(ndc)2(DMF)2 ∙(H2O)4 (1  DMF  H2O) and Zn2(bdc)2(H2O)2 ∙(DMF)2 (2·H2O·DMF), (H2ndc = 2,6-naphthalene dicarboxylic acid, H2bdc = benzene-1,4-dicarboxylic acid and DMF = N,N-Dimethylformamide), were synthesized, characterized and subsequently used for preparing of ZnO nanoparticles. The morphology of initial precursors has direct influence on agglomeration tendency of resulting ZnO nanoparticles. Linkers and coordinated solvent molecules are the two effective factors on the formation of zinc oxide nanoparticles from these metal–organic frameworks.

Graphical abstract

The host and the apohost frameworks of two nano-porous MOFs with similar linkers were used for preparation of ZnO nanoparticles. The influence of guest molecules, coordinated solvent molecules and linker ligands on their morphology and agglomeration process was studied.

      The combination of the abovementioned inherent characteristics of supramolecular compounds with the unique advantages associated with nanomaterials, furthermore expands the breadth of application of nano-supramolecular compounds to a plethora of medical applications [13]. Another novel and extremely attractive application of nano-supramolecular compounds is their role as precursor of nanomaterials such as nano-metal oxides [14–16]. Nano-size CeO2, nanoceria, is a major compound in the useful rare earth family and its properties deviate significantly from those of the bulk material.
