Metal-organic frameworks (MOFs) are very useful nanoporous materials that have attracted much attention in recent years because of their potential in gas storage, separation, luminescence, magnetic materials, and catalysis. Furthermore, in this review, we report the utilization of MOFs as precursors for the synthesis of nanomaterials. In addition to the utilization of MOFs as precursors for the synthesis of nanomaterials with various morphologies, such as nanoparticles, nanorods, and nanosheets, they can be used as a template for the formation of nanomaterials with the same morphology as the initial MOFs. It seems that the apohost of MOFs can be used as a template in the synthesis of nanomaterials. In order to investigate this, we carried out the synthesis of cobalt oxide, copper oxide, nickel oxide, zinc oxide, hematite, and other nanomaterials from MOFs.
In order to evaluation the effects of ultrasonic irradiations, concentration of initial reagents and reaction time on formation [Cu(MBT)] or [Cu(MBT)] copper(I) metal-organic nanomaterials, [HMBT=2-Mercaptobenzothiazole] we designed some experiments and synthesized six samples under different conditions. These nanostructures were characterized by IR spectroscopy, X-ray powder diffraction (XRD) and Scanning Electron Microscopy (SEM). It seems that the tetranuclear cluster of [Cu(MBT)] (2) is the kinetically stable product which is formed at the initial time of the reaction and as the time went, it converts to thermodynamically stable product of [Cu(MBT)] (1) with hexanuclear cluster unit. In the samples which synthesized with low concentration of initial reagents, against to those synthesized with high concentration of initial reagents, the ultrasonic irradiation does not have any effect on formation of any special morphology.
6 -HTA)] n (1), [H 2 TA = terephetalic acid], prepared by sonochemical procedure, to Tl I analogue coordination polymer nanoblocks was studied. The structure of [Tl(μ 3 -HTA)] n (2) is exactly the same as 1 and the Tl ion has distorted octahedral coordination. The carbonyl oxygen is coordinated to two different metal ions, while another oxygen atom is bonded to one metal and participates in a very strong hydrogen bond. Both compounds have secondary straight chain metallophilic interactions. In addition to the same structures of 1 and 2, the same crystal data of them also approved that the chemistry of thallium(I) parallels that of the potassium(I) in many ways.
The cover image, by Elham Mirzadeh et al., is based on the Full Paper Mechanochemical conversion of nano potassium hydrogen terephthalate to thallium analogue nanoblocks with strong hydrogen bonding and straight chain metalophillic interactions, DOI: .
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
