Field-induced slow magnetic relaxation of two 1-D compounds containing six-coordinated cobalt(ii) ions: influence of the coordination geometry

Abstract

Two 1-D Co(ii) compounds with different coordination geometries of the same coordination sphere exhibited field-induced slow relaxation magnetization with different D values.

A self‐penetrating and chemically stable zinc (ii)‐organic framework as multi‐responsive chemo‐sensor to detect pesticide and antibiotics in water

“…One thing to note is the fast‐growing metal organic frameworks (MOFs), which are designed from the perspective of molecules, making full use of the high stability of metal units and versatility of organic linkers, have attracted more and more attention for their potential applications in the fields of adsorption and separation, [ 4–10 ] electrode and photoelectric materials, [ 11–17 ] sensing and detection, [ 18–31 ] catalysis and photocatalysis. [ 32–34 ] Compared with other sensors, such as the conjugated organic probes, nanomaterials, carbon dots, oligomers, the luminescent metal–organic frameworks (LMOFs) possess obvious advantages of enormous structural diversity, adjustable pore size, large surface areas, readily function groups assisted analyte binding, and purposefully implanted active sites, render those LMOFs with the greatest potential as the sensory materials in detecting the POPs.

Multifunctional Properties of a 1D Helical Co(II) Coordination Polymer: Toward Single-Ion Magnetic Behavior and Efficient Dye Degradation

“…If we closely look at the geometry around Co(II) centers of compounds 1 and 2 , compound 1 has distorted trigonal prismatic geometry, which may originate magnetic anisotropy suitable for slow relaxation of magnetization. 12 On the other hand, compound 2 has almost perfect octahedral geometry, which may be responsible for the absence of any slow relaxation of magnetization. 36 The anisotropy parameters of Co(II) centers in compounds 1 and 2 have been calculated by fitting the susceptibility data and magnetization data using PHI software; 37 during the fitting procedure, the g tensor was considered to be isotropic.…”

“…However, the approach of a multinuclear system also has limitations as quite a large number of systems of high-spin ground states fail to yield higher barriers. 12 This shifts the focus away from the multinuclear systems and leads to an alternate strategy, proposed by Waldmann and later on by Neese and Pantazis, 15 of maximizing the relaxation barriers through increasing the magnetic anisotropy. 13,14 Along this line, Ishikawa introduces mononuclear SMMs in terms of the [LnPc 2 ] − ion (Pc = pthalocyanine).…”

Fabrication of a Zn(II)‐Based 2D Pillar Bilayer Metal‐Organic Framework for Antimicrobial Activity

“…Organic‐inorganic hybrid materials, also known as coordination polymers (CPs) or metal‐organic frameworks (MOFs) have been designed and produced in the form of crystals via simple synthetic procedure using metal salts and organic ligands . The potential applications of these compounds such as gas storage and separation, catalysis, electrical conductivity, sensing, magnetism, drug delivery and solar cell can be attained by varying diversity of framework structures of MOFs . Thus, the judicious choice of the metal ion and organic linker leads to the execution of desire applications or properties.…”
