Summary: This paper reports two metal-organic frameworks (MOFs) materials, SUST-WJ-12 and SUST-WJ-13, based on multinuclear clusters with long persistent luminescence (LPL). It is found that both materials exhibit excitation-dependent emission color-tuning and can emit bright and visible LPL for 2-3 seconds after the removal of the excitation light source. Single-crystal X-ray diffraction analysis and theoretical calculations reveal that the LPL is enhanced by the ligand center in the presence of metal clusters. These findings have important implications for applications in lighting and security systems, among others.

Summary: In this study, three metal halide-based complexes exhibiting standard white light emission and excitation-dependent room temperature phosphorescence were synthesized. The bright room temperature phosphorescence is attributed to the crown ether ligand and aggregation state induced by halogen bond. These materials have potential applications in lighting and displaying devices, optical recording devices, and security systems.

Summary: This study reports a unique europium-organic framework containing abundant quasi-OMS with abnormal weak Eu-O bonds, providing reversible binding sites for water molecules and enabling sensitive, visible, and ratiometric luminescent sensing of humidity and water content in organic solvents. The specific recognition of water based on quasi-luminescent-OMSs results in an excellent water detection limit of 0.0003% v/v, one order of magnitude lower than that of the Karl Fischer method.

Summary: Excited-state tuning of luminescent metal-organic compounds has advanced applications in various fields. However, the luminescence lifetimes of these compounds are still limited due to the competition between luminous efficiency and lifetime. This review summarizes recent developments in realizing room-temperature phosphorescence and thermally activated delayed fluorescence, and discusses fundamental materials design, coordination assembly, and factors influencing luminescence properties.

Summary: In this work, organic long persistent luminescence (OLPL) materials with a duration of 20 to 40 minutes are achieved in a simple binary system based on a two-photon ionization mechanism. This system can simultaneously harvest excitons from both singlet and triplet excited states, making it a promising candidate for stable white OLPL. Through modulation and optimization of dopant molecules, the emission profiles of afterglow can be readily tuned to different shades of white with excellent color consistency.

Summary: Recently, researchers synthesized a nontoxic two-dimensional organic-inorganic metal hybrid halides (OIMHs) called PBA(2)[ZnX4], which exhibit stable long persistent luminescence (LPL) emission at room temperature and can be excited by low power sources. The LPL emission comes from the thermally activated charge separation state, and these materials have low cost and high stability.

Summary: Lanthanide metal-organic frameworks (Ln-MOFs) with adjustable structures and wide optical applications are highly studied. However, MOFs with stable framework structures and wide linear pH response in acidic or alkaline solutions are rare. In this study, a new metal-organic framework material was synthesized using 4,4',4''-s-triazine-2,4,6-triyltribenzoate as the organic ligand coordinated with lanthanide ions. The material exhibited a porous three-dimensional square framework structure and emitted red or green fluorescence under 365 nm UV light. The framework showed wide linear pH response (pH=0-14) and could be a potential fluorescence sensing material for pH detection.

Summary: Two new zinc-triazole-carboxylate frameworks were synthesized using a thiophene-containing dicarboxylate and two different triazole ligands. Compound 1 is a 3D anionic porous framework based on dinuclear Zn(II) tetracarboxylate paddlewheel SBUs and dinuclear [Zn-2(tz)(2)] subunits, while compound 2 is a neutral 3D framework based on Zn-triazolate layers and dicarboxylate pillars. Both frameworks exhibit irreversible solid-state structural transformations upon solvent removal/uptake, and show CO2-induced, gate-opening adsorption isotherms at 195 K. Compound 1 selectively adsorbs cationic dyes, while compound 2 hardly adsorbs any selected dyes.

Summary: The study focuses on developing a pore-nanospace post-engineering strategy to optimize the hydrophilicity, water-uptake capacity and air-purifying ability of metal-organic frameworks (MOFs). A moderately hydrophilic MOF (UiO-67-4Me-NH2-38%) with high thermal, hydrolytic and acid-base stability was identified, showing potential for efficient moisture control and pollutants sequestration in confined indoor environments. Exceptional attributes such as water-uptake working capacity/efficiency, contaminants removal, recyclability and regeneration make it a promising candidate for indoor air quality improvement.

Summary: In this study, a Cu(I) metal-organic framework (MOF) with synchronous metal-to-ligand charge transfer (MLCT) state and triplet emission was successfully synthesized. The Cu(I) MOF exhibited MLCT emission in the range of 450-505 nm with microsecond lifetimes and a triplet state emission in the near infrared region at around 705 nm with much longer lifetimes compared to previous reports. The combination of delicate ligand design, enhanced spin-orbital coupling, and tight packing mode of the framework contributed to the generation of MLCT emission and ultralong NIR room temperature phosphorescence.

Summary: Simultaneous removal of ethane and acetylene from a C2-gases mixture for ethylene purification is challenging due to their similar properties. Multifunctional metal-organic frameworks (MOFs) were constructed via dynamic spacer installation (DSI) to optimize the pore-nanospaces for efficient C2H4 isolation. The optimized MOF showed four times higher adsorption capacities for ethane and acetylene than the prototype. This study demonstrates a promising protocol for screening MOFs through porenanospace engineering for challenging separations.
