The combination of single-ion magnets (SIMs) and metal-organic frameworks (MOFs) is expected to produce new quantum materials. principal issue be solved in this regard the development strategies for synthesis SIM-MOFs. This work demonstrates a simple strategy SIM-MOFs where diamagnetic MOF used as framework into which SIM sites are doped. 1, 0.5, 0.2 mol% Co(II) ions doped Zn(II) [CH6 N3 ][ZnII (HCOO)3 ]. MOFs perform with positive D term zero-field splitting. longest magnetic relaxation...
The graphical abstract illustrates antiwear efficiency of studied low SAPS Schiff bases and their copper(<sc>ii</sc>) complexes.
With the aim of creating Cu(II) spin qubits in a rigid metal-organic framework (MOF), this work demonstrates doping 5 %, 2 1 and 0.1 % mol ions into perovskite-type MOF [CH
We report the synthesis, characterization, and electronic properties of quinoid-based three-dimensional metal-organic framework [Fe2(dhbq)3]. The MOF was synthesized without using cations as a template, unlike other reported X2dhbq3-based coordination polymers, crystal structure determined by single-crystal X-ray diffraction. entirely different from [Fe2(X2dhbq3)]2-; three independent 3D polymers were interpenetrated to give overall structure. absence led microporous structure, investigated...
[CuII(chxn)2I]I (chxn = 1R,2R-diaminocyclohexane) has been synthesized, which is the first report of an iodide-bridged Cu(II) chain structure. This compound shows S 1/2 Heisenberg weak antiferromagnetism (J -0.3 cm-1) and magnetic relaxation (τ 43 ms at 1.8 K) with a Raman process in static field.
Guest-promoted modulation of the electronic states in metal-organic frameworks (MOFs) has brought about a new field interdisciplinary research, including host-guest chemistry and solid-state physics. Although there are dozens studies on guest-promoted enhancement electrical conductivity properties, stoichiometry, conductive carriers structure-property relationships have been scarcely studied detail. Herein, we effects continuous controlled bromine vapor doping structural, optical,...
New three-dimensional (3D) lanthanide framework compounds supported by bridging thiocyanate ligand and K+ cations, K4[Ln(NCS)4(H2O)4](NCS)3(H2O)2(1: Ln = Dy, 2: Tb, 3: Gd) have been synthesized. A single-crystal X-ray diffraction study showed that all three were isostructural crystallized in the I 2/a space group. The ion form 2D layers with thiocyanates which are further linked [Ln(NCS)4(H2O)4]- complexes additional ions to generate an interesting 3D structure. Compound 1 shows slow...
A furan-based water soluble fluorescent probe (E)-N′-(2,4-dihydroxybenzylidene)furan-2-carbohydrazide (DBF) has been synthesized and characterized by 1H NMR, 13C ESI-mass spectroscopy single crystal X-ray diffraction techniques.
