Summary: The ligand H3L has been used to study energy transfer in dinuclear lanthanide analogues, showing that ET between Eu-III and Yb-III does not occur significantly, and that Yb-III emission originates from sensitization by the ligand. Energy migration seems to occur between the two Nd-III centers, with Yb-III luminescence being partially sensitized by ET from Nd.

Summary: In this study, a semi-rigid bis-tridentate ligand L was designed and synthesized, which exhibited a trans-to-cis conformational transition when coordinated onto lanthanum ions. By adjusting the metal/ligand ratio, different forms of complexes were obtained. Moreover, the introduction of a chiral auxiliary ligand G(R/S) enabled the transformation of achiral assemblies into chiral complexes. Additionally, a linear enantiomeric excess sensing for the auxiliary ligand was achieved through induced circular dichroism.

Summary: Divalent lanthanide compounds are excellent reducing agents with unique reactivity profiles, but there is currently a lack of effective and selective methods for generating reactive Ln(II) species. This study presents a strategy for generating active Ln(II) from a Ln(III) precursor using a photoexcited chromophore, which is regenerated by a sacrificial reductant. A broad range of reactions can be carried out using this method, with yields and selectivities comparable to or better than stoichiometric transformations.

Summary: Through a combined experimental and theoretical approach, it was shown that unusually high Be-C bond strength in carbene adducts to beryllium compounds can be rationalized by a Be(II) -> N-heterocyclic carbene (NHC) pi back-donation mechanism. This understanding was achieved through energy decomposition analysis and quantum theory of atoms-in-molecules analysis, shedding light on the bonding situation in these complexes.

Summary: The bond distances of [Ln(SST)3(THF)2] compounds were examined, and it was found that the Ln-O(THF) bond changed more significantly than the Ln-O(SST) bond. Further evaluations showed that this enhanced Ln-contraction also occurs in other ligands such as pyridine and halides.

Summary: In this study, vibrational circular dichroism (VCD) spectroscopy was used as an experimental technique to verify DFT-calculated chiral iodane structures. The research revealed that an undescribed cationic chiral iodane was the most common intermediate under oxidative conditions, with significant intramolecular interactions and no significant interactions with potential anionic ligands. Aggregation of the substrates resulted in the formation of a non-coordinating anionic hydrogen bonded complex.

Summary: Polymers often lack the properties required for their intended applications. Additives such as plasticizers, flame retardants, stabilizers, and colorants are used to modify their physical properties to suit the final product. However, colorants pose challenges for recycling technologies as they cannot be removed through reprocessing. The authors have developed a method to prepare colored polymers by adding chromophore monomers to copolymerization reactions, achieving highly colored materials with minimal changes in properties from the base polymer. They have also successfully depolymerized the colored polymers and reformed them into colorless polymers, paving the way for recyclable polymers with tunable properties through the use of dopant-level monomers.

Summary: Gold(II) complexes have been less utilized in catalysis compared to their gold(I) and gold(III) counterparts. However, gold(II) complexes offer potential in homo-coupling and cross-coupling reactions, as they are more easily accessible through simplified oxidation and reduction processes. Gold(II) exhibits characteristics of both soft acid gold(I) and hard acid gold(III). This review explores the unique reactivity and potential applications of gold(II) species, highlighting their significance in catalytic transformations.

Summary: A new aryl selenonium polyoxometalate hybrid was developed and compared with an aryl sulfonium polyoxometalate hybrid in terms of their photocatalytic properties. It was found that the aryl selenonium hybrid exhibited better catalytic performance, which could be attributed to the larger atomic radii of selenium stabilizing the photogenerated electron-hole pair more efficiently. Additionally, the generation of elemental selenium through cleavage of C-Se bonds during catalysis was observed.

Summary: In this work, two metal organic frameworks (MOFs) containing {Cu2I2} clusters, Eu-CuI-INA and Sr-K-CuI-INA, were synthesized and characterized. Both materials have a three-dimensional structure with {Cu2I2} clusters coordinated by INA(-) ligands and Eu3+ or Sr2+ ions. The Sr-K-CuI-INA material exhibited sensitive fluorescence sensing behaviors towards cysteine and nitro-bearing molecules, showing potential applications in bio and explosive molecule sensing.
