The dramatic expansion of data volumes has placed high demands and challenges on optical information technology, and thus the reliable luminescence materials, especially their fatigue resistance during the storage and erasure process are highly considered. Solvent-driven switchable photoluminescence in Sc(DMSO)₆SbCl₆ exhibits promising potential for storing information, which offers a new route in the development of hybrid bimetallic halides for erasable information storage.

AIEgens typically feature dynamic molecular rotor modules, often exhibiting non-planar and conformationally flexible molecular structures. By incorporating AIEgens into the framework of Metal-Organic Frameworks (MOFs) as functionalized linkers, one can effectively overcome the geometric constraints inherent in traditional, rigid "static" linkers, while simultaneously circumventing the major bottleneck associated with traditional organic fluorophores—namely, their propensity for fluorescence quenching in the aggregated state. The self-assembly of dynamic Lanthanide Metal-Organic Frameworks (LnMOFs)—formed by the alternating linkage of lanthanide ions or clusters (serving as Secondary Building Units, or SBUs, and possessing exceptional photophysical properties and fingerprint emission spectra) with dynamic molecular rotors (serving as linkers)—opens up new horizons for the construction of novel, intelligent luminescent materials. The degree of twisting within the molecular rotors of the AIEgen ligands—and the consequent changes in energy levels resulting from conformational shifts—enables an adaptive "antenna effect" tailored to the distinct energy levels of various lanthanide ions, thereby facilitating the effective construction of intelligent multicolor and/or chromogenic materials.

A new review in Nano Research systematically details the latest advances in quantum dot (QD) technology for point-of-care testing (POCT). Through precise material engineering strategies, QDs can advance the development of various high-sensitivity sensing technologies. Although challenges remain in biosafety and device integration, the coordinated development of "greening, intellectualization, and integration" is driving quantum dot technology from the laboratory toward practical application.

Understanding how crystal facets dictate the adsorption mechanisms of multifunctional oxides is crucial for designing selective materials for fluorine-containing contaminants.

Researchers at Southern University of Science and Technology established the structure–facet–function correlation in CeO₂, unveiling dual active-site mechanisms that differentiate inorganic and organic fluorine adsorption and offering mechanistic insights for rational design of advanced fluorine-selective materials.

A research team has successfully engineered “frustrated Lewis pairs” (FLPs) on graphitic carbon nitride, creating a highly efficient photocatalyst that activates and degrades tetracycline in water nearly four times faster than conventional materials. The unique “push-pull” electron effect of FLPs facilitates molecular polarization and stepwise decomposition, steering the reaction toward less toxic intermediates and offering a promising sustainable solution for antibiotic-contaminated wastewater treatment.

Three novel cobalt(II) complexes have been synthesized to investigate the spin crossover behavior. The study highlights how counteranions and the solvents strictly tune magnetic properties and induce spontaneous resolution into chiral crystals, promoting the development of multifunctional molecular materials that combine switchable magnetism with optical and chiral features.

The incorporation of oxygen functional groups (OFGs) into cobalt-nitrogen-carbon (CoNC) catalysts is widely regarded as a promising strategy for enhancing hydrogen peroxide (H₂O₂) electrosynthesis via the two-electron oxygen reduction reaction (2e⁻ ORR). A new study challenges the long-held belief that oxygenated groups enhance CoNC catalysts' H₂O₂ production, offering critical insights for sustainable electrocatalysis.
