Conducting single-molecule magnet materials
Multifunctional molecular materials exhibiting electrical conductivity and single-molecule magnet (SMM) behaviour are particularly attractive for electronic devices and related applications owing to the interaction between electronic conduction and magnetization of unimolecular units.
Slow magnetic relaxation influenced by change of symmetry from ideal Ci to D3d in cobalt(II)-based single-ion magnets
Two mononuclear complexes including the same cation [Co(imidazole)6]2+ and the different symmetries Ci and D3d showed discriminatively slow magnetic relaxation.
Structural, magnetic and theoretical analyses of anionic and cationic phthalocyaninato-terbium(III) double-decker complexes: Magnetic relaxation via higher ligand-field sublevels enhanced by oxidation
Tetrairon(II) extended metal atom chains as single-molecule magnets
The iron(II)-based extended metal atom chains [Fe4(tpda)3X2] (X = Cl, Br) have a weakly magnetic ground state but display SMM properties, which are detectable even in zero DC field when X = Br.
A new class of DyIII-SIMs associated with a guanidine-based ligand
The diverse relaxation dynamics of a series of DyIII-based SIMs resulting from the coordinated molecules and counter anions were elucidated by structural analysis, magnetic investigations and ab initio calculations.
A trapped hexaaqua CoII complex between the polyanionic sheets of decavanadate reveals high axial anisotropy and field induced SIM behaviour
A hexaaqua CoII complex within the anionic metal oxide cluster of decavanadates reveals easy-axis anisotropy and field induced SIM behaviour with a high energy barrier for the spin reversal process.
Slow magnetic relaxation in penta-coordinate cobalt(II) field-induced single-ion magnets (SIMs) with easy-axis magnetic anisotropy
Two penta-coordinate [Co(Ln)(NCS)]ClO4 with substituted pyridyl based bispyrazolyl ligands have been structurally characterized. The complexes show an easy-axis magnetic anisotropy, large rhombicity and slow relaxation of magnetization.
Radii-dependent self-assembly of chiral lanthanide complexes: synthesis, chirality, and single-molecule magnet behavior
Here we report the radii-dependent self-assembly of chiral lanthanide complexes and the single-molecule magnet behavior of the Dy5 complexes.
Structure and magnetic properties of a novel heteroheptanuclear metal string complex [Ni3Ru2Ni2(μ7-teptra)4(NCS)2](PF6)
A novel heteroheptanuclear metal string complex was synthesized by using nickel and ruthenium metal ions to explore the electronic structure and magnetic property.
The slow magnetic relaxation regulated by the coordination, configuration and intermolecular dipolar field in two mononuclear DyIII single-molecule magnets (SMMs)
Tuning the magnetic dynamics of single-molecule magnets (SMMs) is a crucial challenge for chemists.
A difunctional azido-cobalt(II) coordination polymer exhibiting slow magnetic relaxation behaviour and high-energy characteristics with good thermostability and insensitivity
As a difunctional material, an azido-Co(II) coordination polymer with a high-nitrogen content exhibits both molecule-based magnetic behaviour and high-energy performance with superior thermostability and insensitivity.
3D LnIII-MOFs: slow magnetic relaxation and highly sensitive luminescence detection of Fe3+ and ketones
Five Ln-MOFs were obtained: the Dy-MOF shows slow magnetic relaxation, and the Eu-MOF and Tb-MOF show selective and sensitive sensing towards Fe3+ ions and ketones in a water system.
Magnetic properties and structure of tetranuclear lanthanide complexes based on 8-hydroxylquinoline Schiff base derivative and β-diketone coligand
Herein, we report the synthesis, structure, and magnetism of five tetranuclear LnIII complexes encapsulated by 5-(4-pyridinecarboxaldehyde)amino-8-hydroxylquinoline and β-diketonate coligand.
About this collection
Welcome to a Spotlight themed collection published by Dalton Transactions.
The research area of molecule-based magnets encompassing single-molecule magnets (SMMs), single-ion magnets (SIMs) and single-chain magnets (SCMs) has been extremely active in recent years. This field is truly interdisciplinary and the advances in this field have been possible only due to a concerted effort from synthetic coordination- and organometallic chemists, physicists, materials scientists, and theoreticians. Research in this field is driven by both academic curiosity as well as the possibility of finding exotic applications such as high-density information to quantum computation. While many challenges remain to be overcome before the potential of these new materials can be realized, there has been substantial progress both in the design and assembly of these new systems as well as in understanding of their properties. This appears to be an appropriate time to bring out a special edition of Dalton Transactions on this multi-disciplinary subject.
This collection is guest edited by Dalton Transactions Associate Editor Vadapalli Chandrasekhar (Indian Institute of Technology Kanpur).
Articles will be added to this themed collection as soon as possible after they are published. Please return to this page frequently to see the collection grow.
