Constructing high axiality mononuclear dysprosium molecular magnets a regulation-of-co-ligands strategy.

Two lanthanide complexes with formulae [Dy(L)(pentafluoro-PhO)] (1) and [Dy(L)(2,6-difluoro-PhO)](BPh) (2) (L = 2,14-dimethyl-3,6,10,13,19-pentaazabicyclo[13.3.1]nonadecal (19),2,13,15,17-pentaene) were structurally and magnetically characterized.

Multifunctional lanthanide-based single-molecule magnets exhibiting luminescence thermometry and photochromic and ferroelectric properties.

Lanthanide-based single-molecule magnets (SMMs) have captivated the attention of researchers due to their great potential application in quantum information processing, storage, spintronics . Recent years have witnessed continuous breakthroughs in the field of SMMs, which make them very promising to be used in future practical functional applications. However, there remain formidable obstacles involving suppression of the quantum tunneling of magnetization (QTM) to maximize magnetic anisotropy, integrating and applying them in devices .

One-Dimensional Chain Viologen-Based Lanthanide Multistimulus-Responsive Materials with Photochromism, Photoluminescence, Photomagnetism, and Ammonia/Amine Vapor Sensing.

In this work, a series of novel multistimulus-responsive lanthanide coordination polymers {[LnL(HO)]Cl·3HO} (Ln = Dy, Tb, Eu) constructed using a dicarboxylic acid viologen derivative L (L = ,'-4,4'-bipyridiniodipropionate) and LnCl·6HO were prepared. All materials showed positive responses to UV light, and the photochromic phenomena accompanied by significant photoquenching of photoluminescence could be observed through a photoelectron transfer mechanism. Strikingly, the Dy analogue displayed photomagnetic behavior, as well as responded positively to small molecules of inorganic ammonia/organic amines.

Highly Performant Electromagnetic Absorption at the X Band Based on Co@NCS/TiCT Composites.

Electromagnetic waves at the X band (8.2-12.4 GHz) play significant roles in military applications such as radar, satellite, and wireless communication.

Di- and Tetranuclear Dysprosium Single-Molecule Magnets Bridged by Unprecedentedly Disassembled Nitrogen-Enriched Tetrazine Derivatives.

A series of di- and tetranuclear lanthanide complexes with the formulas [Dybmzch(tmhd) (CHOH)]·CHOH (), [Dybmzch(dbm) (CHO)(CHOH)]·0.5CHOH·0.5HO (), and Dybmzch(btfa) (), where tmhd = 2,2,6,6-tetramethyl-3,5-heptanedionate, dbm = dibenzoylmethane, btfa = benzoyltrifluoroacetone, and bmzch = ()--[()-pyrimidin-2-ylmethylene]pyrimidine-2-carbohydrazonate, were structurally and magnetically characterized.
