Summary: In this study, a series of photochromic rare-earth complexes were synthesized using hexaazamacrocyclic ligand LN6, and the photogenerated radicals of the ligands were revealed for the first time. The complexes 1-Ln showed photochromic behavior upon 365 nm light irradiation, induced by the photo-generated radicals. Static and dynamic magnetic studies showed weak ferromagnetic interactions among DyIII ions and photogenerated LN6 radicals in 1-Dy and its irradiated product 1-Dy*. Time-dependent fluorescence measurements demonstrated the quenching dynamics of lanthanide in the photochromic process, with a high quenching efficiency in the irradiated product 1-Eu*.

Summary: In this study, a tridentate N,N,O ligand (LNO2H) was used to synthesize two neutral structurally similar complexes. X-ray single-crystal diffraction analysis confirmed the octahedral geometry of LnIII ion in both complexes. Magnetic studies showed that complex 1 exhibited single ion magnet (SIM) behavior with an effective energy barrier of 34.16 K. Ab initio calculations were performed to extract the magnetic relaxation dynamics of complexes 1 and 2.

Summary: Two isomeric Co(ii) complexes with the same molecular formula of [Co(napy)(2)(NO3)(2)] (napy = 1,8-naphthyridine) were synthesized and their structures were determined. The complexes exhibit highly irregular six-(1) and seven-coordinate (2) geometries. Magnetic measurements, X-band EPR data, and theoretical calculations were conducted to investigate their properties, revealing field-induced slow magnetic relaxation in both complexes, with 2 attributed to an easy-plane anisotropy.

Summary: A new octahedral luminescent Single-Molecule Magnet (SMM) with massive crystal-field splitting and an anisotropic barrier of 1385 cm(-1) is reported, with a unique mechanism behind the high blocking barrier revealed through magnetic measurements and ab initio analysis. The novel mechanism involves quenching of one-phonon transitions between low-lying crystal-field multiplets, forcing relaxation to proceed through a fourth doublet. The short relaxation time observed is attributed to non-axial anisotropy and tunnelling relaxation path via interaction with nuclear spins.

Summary: This Review discusses the recent trends in key synthetic strategies for achieving exotic magnetic properties and provides representative seminal reports. Special emphasis is given to monomeric high-performance Dy(III)-SMMs realized through crystal field, predominant bond, and organometallic approaches, as well as stimulating reports on endometallofullerenes and radical-bridged systems with strong magnetic coupling. The role of spin-vibration coupling in magnetic relaxation is also highlighted. More demanding theoretical studies are anticipated to predict promising molecules with magnetization blocking at practical temperatures.

Summary: This article provides an overview of single-ion magnetism in lanthanide(III)-based coordination frameworks, which consist of self-assemblies in one-, two-, and three-dimensions. Lanthanide(III) ions with their large magnetic moments and magnetic anisotropy are potential candidates for SIMs/SMMs. The multi-functionalities of the coordination framework structure, such as responsiveness to external stimuli, proton conduction, high structural stability, and host-guest interactions, make lanthanide(III)-based magnetic metal coordination frameworks an exciting platform for the development of a new generation of SIMs/SMMs.

Summary: This paper reports the high adsorption of benzene at low pressure and efficient separation of benzene/cyclohexane achieved by controlling the pore chemistry of two families of robust metal-organic frameworks, UiO-66 and MFM-300. UiO-66-CuII exhibits exceptional adsorption of benzene at 3.92 mmol g-1 and MFM-300(Sc) shows a high selectivity of 166 for the separation of benzene/cyclohexane (v/v = 1/1) mixture. The binding mechanisms of benzene and cyclohexane in these materials are revealed through in situ synchrotron X-ray diffraction, neutron powder diffraction, and multiple spectroscopic techniques. Reversible binding of benzene at an open Cu(II) site within metal-organic frameworks is also visualized for the first time.

Summary: This study found that [FeL2]X-2 center dot 2H(2)O (L = 2,6-bis{5-methyl-1H-pyrazol-3-yl}pyridine; X- = BF4- or ClO4-) can be dehydrated by mild heating. The anhydrous [FeL2][BF4](2) exhibits a spin transition with thermal hysteresis, while the isomorphous [FeL2][ClO4](2) remains high spin on cooling, likely due to kinetic inhibition of its spin transition.

Summary: This study presents the design and synthesis of sulfated disaccharide inhibitors based on IdoA(2S)-GlcNS(6S), which showed potent inhibition of Sulf-2. The results suggest that IdoA(2S)-GlcNS(6S) is the shortest fragment size required for effective inhibition of Sulfs, and a trisulfated disaccharide is identified as the minimal fragment size of heparan sulfate for effective endosulfatase inhibition.

Summary: The self-adaptability of galvanostatic electrolysis was found to be helpful in a multistage chemo- and diastereoselective electrochemically promoted cyclodimerization of chalcones. Through a series of reductive events, densely functionalized cyclopentanes with five contiguous stereocenters were obtained (25 examples, yields up to 95%, dr values up to >20:1). Further experimental and electrochemical investigations indicated the crucial role of dynamic kinetic resolution of the aldol intermediate in the reaction mechanism.
