In this work, a novel stable zirconium-based metal-organic framework (Zr-MOF) with the formula [Zr6O4(OH)4(PVDC)6]4·66DMF (Zr-1, H2PVDC = (E,E)-2,5-dimethoxy-1,4-bis[2-(4-carboxylatestyryl)]benzene; DMF N,N-dimethylformamide) was synthesized by introducing linear phenylenevinylene-based carboxylate ligand to react ZrCl4 under solvothermal conditions. According single-crystal X-ray diffraction measurement, complex Zr-1 featured 2-fold interpenetrated framework, in which single coordination possessed structure similar that of well-known Zr-MOF, UiO-66, constructed from [Zr6O4(OH)4]12+ clusters and ligands PVDC2-. Due introduction phenylenevinylene-functionalized ligand, exhibited unique fluorescence sensing performance toward permanganate (MnO4-) different concentrations. At low concentrations, emission intensity around 510 nm enhanced significantly an increase concentration MnO4- aqueous suspension. However, while excess added into suspension, decreased significantly, peak turned five peaks upon addition MnO4-. Such phenomenon has been scarcely reported previous MOF-based sensors. Moreover, showed high anti-interference capability for detection both at This work may pave new way development platforms.

Lanthanide metal–organic frameworks (Ln-MOFs) represent a promising class of multicolor luminescence nanomaterials with broad application prospects. However, the fabrication high-quality, tunable Ln-MOFs for optical applications remains highly challenging due to lack suitable processing methods. In this work, an integrated device was introduced that used dielectric barrier discharge (DBD) liquid plasma synthesis, which coupled in situ spectral monitoring, enabling heterojunction Ln-MOFs. This approach facilitates precise control from red, orange-red, yellow, and pale-green green by adjusting Tb3+-to-Eu3+ ratio based on real-time data. The architecture effectively suppresses undesired direct energy transfer, commonly occurs mixed-metal structures. fabricated were characterized using X-ray diffraction, infrared spectroscopy, UV–vis scanning electron microscopy, photoluminescence techniques. studies demonstrated these hold significant promise development anticounterfeiting materials across wide range applications.
