Multifunctional materials, combining diverse physical properties, are the candidates for the new generation of smart devices realizing many tasks simultaneously. Particular attention is given to single-phase multifunctional materials offering the...

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.…”

“…[287] This was updated in 2020, [162] by C. Train et al targeting MChD as an optical readout of magnetic data with unpolarized light. Magnetochiral anisotropy was commented on several examples, including 4 f molecules in 2021 [288] In 2021, [289] D. Pinkowicz et al reviewed recent results on helicene-4 f complexes in the framework of chiral lanthanide complexes, while in 2023 [280] the already mentioned review by S. Chorazy et al complemented the field.…”

Covalency versus magnetic axiality in Nd molecular magnets: Nd-photoluminescence, strong ligand-field, and unprecedented nephelauxetic effect in fullerenes NdM2N@C80 (M = Sc, Lu, Y)

“…Optical spectroscopy can contribute to the understanding of the SMM properties by the analysis of the fine structure of f–f transitions, in particular in low-temperature photoluminescence (PL) spectra, and by the correlation of the determined level splitting with magnetic behaviour. 1–5 Since the first report on the Dy(DOTA) complex by Sessoli et al in 2012, 6 the vast majority of such studies were devoted to Dy 6–17 and Yb 8,18–25 complexes, with rare instances of Tb, 8,26–28 Ho, 29 Nd, 30–33 and Er SMMs. 34,35 Recent trends also include a development of luminescence thermometry based on the temperature-dependent PL of Ln-SMMs, 2,21,29,36,37 and the use of lanthanide complexes with a narrow optical linewidth for photonic quantum technologies.…”

SHG-active luminescent thermometers based on chiral cyclometalated dicyanidoiridate(iii) complexes

“…[28][29][30][31] Aiming at extreme miniaturization and optimized efficiency of devices suitable for many applications, the construction of multifunctional materials became an emerging concept. 32,33 One route of its realization relies on linking optical phenomena, such as the above-mentioned luminescence, including luminescent thermometry, and NLO activity with other physical functionalities, e.g., magnetic or electrical ones. [34][35][36][37][38][39][40][41][42] As a result, the unique groups of emissive and SHG-active molecular nanomagnets or ferroelectrics, [34][35][36][37][38][39] as well as advanced systems combining luminescent thermometry with nanomagnetism and/or ionic conductivity, [40][41][42] were reported.…”
