Slow relaxation of the magnetization, reversible solvent exchange and luminescence in 2D anilato-based frameworks

Abstract

The series of multifunctional 2D frameworks prepared with Dy(III) and the bromanilato ligand formulated as: [Dy2(C6O4Br2)3(G)n]·nG with G = H2O, dimethylformamide (dmf) and dimethylsulfoxide (dmso) can exchange the coordinated and...

A Multifunctional Dysprosium‐Carboxylato 2D Metall–Organic Framework

“…[5] Inorganic 2D materials are used to exploit proximity effects on graphene,b eing magnetic 2D metal-organic frameworks (MOFs) an alternative to the known 2D inorganic materials. [6] Thechemical control provided by coordination chemistry can be exploited in this area, making possible defect-free 2D nanosheets,t ot une aggregation of the nanosheets,a ss hown by Choi and co-workers,bymodifying the ligand in ways that do not affect the binding sites, [7] to form 2D materials for planar qubits, [8] or to provide multifunctional properties to the material by ligand functionalization, as is currently done for coordination complexes that combine multiple properties like magnetism and luminescence [9][10][11][12][13][14][15] or photochromism. [16,17] There are already several examples of 2D MOFs,usually relying in polytopic planar ligands or molecules that afford ac oordination network in two dimensions with suitable linkers.…”

Slow Magnetic Relaxation in a Co2Dy Trimer and a Co2Dy2 Tetramer

“…The presence of a Direct mechanism in the relaxation of the magnetization found in complex 2 when H DC =500 Oe is not very common in Dy(III) complexes, but has already been observed on other Dy(III) complexes (see table 2) [47–51] …”

Luminescent and Magnetic Tb-MOF Flakes Deposited on Silicon

“…Another interesting possibility concerns the development of multifunctional complexes that incorporate multiple properties such as magnetism and luminescence [21][22][23][24][25][26][27][28] or photochromism [29,30].…”
