Detailed DFT and ab initio calculations unveil the correlation between spin–phonon vibrations blocking temperature to provide design clues improve single-ion magnet characteristics in pseudo- D 5h family of Dy( iii ) SMMs.
The recent breakthrough of attaining blocking temperature near liquid N2 rekindled the interest in lanthanide-based Single Molecule Magnets (SMMs) towards end-user applications. Within this realm, several challenges are present,...
The mechanistic investigations between Cu(II) and the anisotropic lanthanides (Ln(III)) are not much explored to date. This is due complicated energy spectrum which arises orbital angular momentum of lanthanides. Interestingly, exchange coupling J in Ln(III)–Cu(II) systems was found be antiferromagnetic for <4f7 metal ions ferromagnetic ≥4f7 ions, while net magnitude JTotal strength gradually decreases moving from f1 f13. While this established several examples, reason intriguing trend...
The recently reported compound [DyIIILF](CF3SO3)2·H2O (L = 1,4,7,10-tetrakis(2-pyridylmethyl)-1,4,7,10-tetraaza-cyclododecane) displays a strong axial magnetic anisotropy, due to the short Dy-F bond, and single-molecule magnet (SMM) behavior. Following our earlier [DyIIILF]2+ work, herein we report systematic structural study of family [LnIIILF](CF3SO3)2·H2O compounds (Ln(III) 1-Ce, 2-Pr, 3-Nd, 4-Eu, 5-Tb, 6-Ho, 7-Er, 8-Tm, 9-Yb). From this series, Ce(III) Nd(III) analogues show slow...
The present work is part of our ongoing quest for developing functional inorganic complexes using unorthodox pyridyl-pyrazolyl-based ligands. Accordingly, we report herein the synthesis, characterization, and luminescence magnetic properties four 3d-4f mixed-metal with a general core Ln2Zn6 (Ln = Dy, Gd, Tb, Eu). In stark contrast to popular wisdom compartmental ligand separate islands hard soft coordinating sites selective coordination, have vindicated approach overcrowded N-coordinating...
Three mononuclear cobalt(II) tetrahedral complexes [Co(CzPh2PO)2X2] (CzPh2PO = (9H-carbazol-9-yl)diphenylphosphine oxide and X Cl (1), Br (2), I (3)) have been synthesized using a simple synthetic approach to examine their single-ion magnetic (SIM) behavior. A detailed study of the variation in dynamic properties Co(II) ion ligand field has carried out by change halide ligand. The axial zero-field splitting parameter D was found vary from −16.4 cm–1 1 −13.8 2 +14.6 3. All new exhibit...
Magnetic exchange coupling (J) is one of the important spin Hamiltonian parameters that control magnetic characteristics single-molecule magnets (SMMs). While numerous chemical methodologies have been proposed to modify ligands and J value, magneto-structural correlations developed accordingly, altering this parameter through non-chemical means remains a challenging task. This study explores impact an Oriented-External Electric Field (OEEF) on over twenty lanthanide-radical complexes using...

This study presents the first-ever investigation of spin-phonon coupling mechanisms in fullerene-based single-molecule magnets (SMMs) using ab initio CASSCF combined with DFT calculations. While lanthanide-based SMMs, particularly those DyIII ions, are known for their impressive blocking temperatures and relaxation barriers, endohedral metallofullerene (EMFs) offer a unique platform housing low-coordinated lanthanides within rigid carbon cages. We have explored spin dynamics DyScS@C82...
At the cutting edge of high-performance single-molecule magnets (SMMs) lie lanthanide-based complexes, renowned for their potent magnetic anisotropy. The performance SMMs is measured generally via barrier height magnetization reversal (Ueff) and blocking temperature (TB), below which fully frozen. To enhance Ueff TB values in SMMs, static crystal field splitting mJ levels has been effectively adjusted through ligand design, leveraging oblate/prolate ground state 4f electron density shape....
The recent breakthrough of attaining blocking temperature near liquid N2 rekindled the interest in lanthanide-based Single Molecule Magnets towards end-user applications. Within this realm, several challenges are present, with a key objective being further enhancement temperature. As current set molecules based on Dy(III) has already reached their maximum potential barrier height for magnetization reversal (Ueff), chemical insights-based developments hampered. In connection, using DFT and ab...
Generating plasmonic hot-spots through engineering of nanoscale interfaces offers exciting opportunities towards point-of-care analytical detection. The mutual trade-off between ultra-high sensitivity, specificity and reliability are major drawbacks for practical applicability with real-time samples. Fundamentally these originate from low photonic mode density, high ohmic losses, temporally fluctuating chemically indistinguishable nature electromagnetic hot-spots. This work describes...
