Get under the Umbrella: A Comprehensive Gateway for Researchers on Lanthanide‐Based Single‐Molecule Magnets

“…Multifunctional 4 f-SMM were further reviewed in 2023 [280] by S. Chorazy et al focused on multi-functionality of luminescent 4 f-SMM; additionally, molecules with stimuli response, electrical functionalities (proton conductivity or ferroelectricity), and chirality-based optical properties (Circularly Polarized Luminescence (CPL) and magneto-chiral effect (MChD),…) are also reviewed. Similarly in 2023, [281] Sun et al, reviewed multifunctional 4 f-SMM with luminescence thermometry, photochromic and ferroelectric properties. Same year, [279] M. Perfetti et al reviewed how the chemical tuning of the energy gap between the ground and first excited state and tailoring the magnetic anisotropy (mainly 4 f) allow the production of multifunctional magnetic materials with potential technological relevance (Figure 24).…”

Recent advances in lanthanide-based POMs for photoluminescent applications

“…Lanthanide (Ln)-based luminescent materials with the high color purity of the emitted light have attracted considerable attention in broad areas of sciences as potent candidates owing to their resistance to photobleaching, narrow f–f transitions, and long excited-state lifetimes. 21–23 Trivalent Ln III ions with many complicated 4f energy levels, known as the “vitamins of modern industry”, feature fluorescence emission via intra-4f or 4f–5d transitions from visible (Eu III or Tb III ) to near-infrared (Nd III or Yb III ) light. 22,24–29 This property can ensure the emergence of Ln ions with high color purity and Stokes shift, reducing excitation interference in the emission process.…”

Spectroscopic techniques to probe magnetic anisotropy and spin–phonon coupling in metal complexes

“…, Wernsdorfer and coworkers. 92–95 In addition, electronic structures in metal complexes have been determined by spectroscopic techniques such as magnetic circular dichroism (MCD), 30,48,96–99 luminescence, 100–104 and FIRMS. For us, finding spectroscopic methods to directly determine energies of magnetic excited states that are >33 cm −1 , i.e.…”
