Summary: Metal-organic framework (MOF) nanomaterials exhibit matrix coordination-induced emission and quenching effects, with their fluorescence regulated by the ligand-to-metal charge transfer process. This LMCT process acts as a fluorescent switch in MOF nanomaterials, regardless of their morphology, even when ground into amorphous structures.

Summary: Synthetic photonic materials exploiting PT symmetry are revolutionizing the photonic sciences. However, current PT-symmetric microcavity laser systems suffer from limited laser spectral bandwidth. In this study, a reconfigurable PT-symmetric microcavity system with controllable complex refractive indices is proposed using an organic composite material system and a grayscale electron-beam direct-writing technique. The introduction of organic photoisomerizable compounds enables dynamically tunable single-mode laser output.

Summary: This study synthesized Ln-MOFs phosphors with tunable luminescence color and applied them in white LEDs. The emission color of the phosphors can be modulated by changing the molar ratio of the raw materials. Ln-MOFs showed excellent thermal stability and achieved white light emission when mixed with blue phosphors.

Summary: Metal-organic framework materials (MOFs) and MOFs-based composites have been widely used for adsorbing heavy metals due to their large surface area and porosity. In this study, MOF-801 and its composite Fe3O4/MOF-801 were prepared and used as adsorbents to capture Se(IV) in water solution. The maximum adsorption capacity of Fe3O4/MOF-801 was higher than MOF-801, and coexisting anions had minimal effect on Se(IV) adsorption. The mechanisms of Se(IV) removal by the two adsorbents were thoroughly analyzed using Zeta potential, FTIR, and XPS. XPS analysis confirmed the presence of charge transfer in Fe3O4/MOF-801, which facilitated Se(IV) adsorption and reduction.

Summary: Metal-organic frameworks (MOFs)-mediated photocatalysis is a promising solution to address energy shortage and environmental pollution. Significant progress has been made in the modification strategies for improving the photocatalytic performance of MOFs, as well as in understanding the mechanisms, such as the excitonic effect. This work critically reviews the excitonic effects in charge transfer and energy transfer processes, summarizes common techniques for characterizing excitonic effects, discusses strategies for regulating excitonic behaviors, and provides insights into the current challenges and future perspectives of MOFs-mediated photocatalysis for energy conversion and environmental remediation.

Summary: Optical anticounterfeiting tags utilize the photoluminescent properties of materials to encode unique patterns for identification and validation. Metal-organic frameworks (MOFs) based on polynuclear rare earth clusters are ideal materials for this purpose due to their fine control over structure and composition. In this study, we designed and synthesized heterometallic MOFs using Eu, Nd, and Yb with a specific linker. The resulting optical tags have multiple covert elements, with invisible emissions from Eu and infrared emissions from Nd and Yb. We also discovered a previously unobserved 11-metal cluster correlated with the presence of Yb in the MOFs. These materials demonstrate great potential as intricate optical tags and highlight the importance of linker selection in controlling their photoluminescent properties.

Summary: Metal-organic frameworks (MOFs) with highly modulable structures and components have the potential to be used as tunable luminophores. In this study, two MOF luminophores based on Cd(II) ions, 1,3,5-tri(4-pyridinyl)benzene (TPB), and 1,4-dicarboxybenzene (H2BDC) were constructed. The fluorescence properties and structure of MOFs were investigated, showing that the fluorescence of MOF-2 can be regulated by the amount of anthracene feeding.

Summary: Structural modifications to molecular systems that control photon emission processes are crucial for the development of fluorescence sensors, X-ray imaging scintillators, and OLEDs. This study explored the effects of slight changes in chemical structure on interfacial excited-state transfer processes using two donor-acceptor systems. The results showed efficient energy transfer in the SDZ-TADF system and both energy and electron transfer processes in the Ac-SDZ-TADF system. Transient absorption measurements and TD-DFT calculations confirmed the occurrence of photoinduced electron transfer in the Ac-SDZ-TADF system. This work provides a straightforward approach to modulate excited-state energy/charge transfer processes at donor-acceptor interfaces.

Summary: A strategy was proposed to design spherical MOFs microcavities by introducing flexible building blocks to overcome scattering losses in MOF microstructures, resulting in high Q factor and sufficient feedback for high-quality lasing oscillations. The acquired spherical microcavities with ultra-smooth surfaces and circular boundaries may pave the way for new types of flexible MOF-based photonic components.

Summary: The introduction of donor-acceptor motifs into organic semiconductors is an effective strategy to regulate photocatalytic activity. In this study, benzodithiophene-based covalent triazine framework materials (BDT-CTFs) with donor-acceptor motifs were reported. It was found that adjusting the D/A ratio in the BDT-CTF photocatalytic materials can modify the band positions, band gaps, and electron-hole separation efficiency. The high photocatalytic hydrogen evolution reaction (HER) activities of BDT-CTF-1 materials are attributed to their high electron-hole separation and migration efficiency, low electron-hole recombination rates, and special donor-acceptor pore structures. This research provides insights into the structure-activity relationship in BDT-based CTFs and offers a strategy for developing high-performance organic photocatalysts.
