Guest-dependent single-ion magnet behaviour in a cobalt(ii) metal–organic framework

Efficient removal of cobalt(II) ion from aqueous solution using amide-functionalized metal-organic framework

In this study, an amide-functionalized metal-organic framework, namely TMU-24 was selected to adsorb Co(II) from wastewater with an adsorption capacity of 500 mg. g-1 in less than 20 minutes in neutral pH (pH=7). The effect of diverse parameters such as adsorbent dosage, competitive ions, and contact time on the adsorption process was investigated to find the optimal amounts of them. Also, the ...

In this paper, the effect of nanocatalytic metal-organic framework based on copper metal and bis-tetrazolamine (CuBTA) ligand functionalized with cobalt (II) oxide nanoparticles on the thermal decomposition behavior of ammonium perchlorate (AP), using differential survey calorimetry (DSC) has been reviewed. First, the metal-organic framework (CuBTA) was synthesized from the raw materials of cop...

Reversible solvatomagnetic switching in a single-ion magnet from an entatic state.

A vast impact on molecular nanoscience can be achieved using simple transition metal complexes as dynamic chemical systems to perform specific and selective tasks under the control of an external stimulus that switches "ON" and "OFF" their electronic properties. While the interest in single-ion magnets (SIMs) lies in their potential applications in information storage and quantum computing, the...

Single ion magnet behaviour in a two-dimensional network of dicyanamide-bridged cobalt(II) ions.

A novel two-dimensional coordination polymer of the formula [Co(dca)2(atz)2]n () resulted from assembling trans-bis(2-amino-1,3,5-triazine)cobalt(ii) motifs by dicyanamide spacers. Variable-temperature dc and ac magnetic susceptibility measurements of show that the high-spin cobalt(ii) ions act as single ion magnets (SIMs).
