Article Abstract
UiO-66 analogues are good candidates as stationary phase in HPLC because of their chemical/thermal stability, large surface area, and two cage structures. Here, two UiO-66 analogues, UiO-66-NH2 and UiO-67, were synthesized and used as stationary phase in HPLC to evaluate their performance in the separation of substituted benzenes (SBs) and polycyclic aromatic hydrocarbons (PAHs). The results showed that SBs could be well separated on UiO-66-NH2 column but not on UiO-67 column. Nonetheless, PAHs could be well separated on UiO-67 column. The separation mechanisms of SBs and PAHs on UiO-66 analogues may be involved in the pore size and functional group in the frameworks of UiO-66 analogues. Introduction of the-NH2 into UiO-66 significantly reduced its adsorption capacity for SB congeners, which resulted in less separation of SBs on UiO-66-NH2. As for the separation of PAHs on UiO-67 column, the π-π stacking effect was supposed to play a vital role.

To overcome the limitations of conventional enzymatic glyphosate (Glyp) detection methods, including enzyme environmental sensitivity, high cost, and limited enzyme sources, this study developed a portable paper-based fluorescence platform (Y-R membrane) based on a metal-organic framework (MOF)-driven fluorescence regulation mechanism for non-enzymatic and rapid detection of Glyp. This platform was constructed by immobilizing MnMOF and yellow carbon dots (Y-CDs) on a polyvinylidene fluoride membrane. The ZrOx-OH derived from alkaline-treated UiO-66 regulated the Mn/Mn redox reactions through its surface hydroxyl groups, triggering the red fluorescence of MnMOF.

Conventional syntheses of robust Zr-based metal-organic frameworks (Zr-MOFs) rely on harsh solvothermal conditions, precluding the inclusion of fragile functionalities such as enzymes or organisms. Therefore, developing routes to such stable frameworks under ambient conditions remains a significant challenge. Here, we report a mild aqueous solid-state crystallization (SSC) strategy that enables Zr-MOF assembly at ambient temperature.

Development of nanozymes with enhanced activity and specificity can be profitable for sensitive and anti-interference biosensing. Herein, we developed a protonation strategy to fabricate metal-organic framework-confined Au nanoclusters with enhanced catalytic activity and specificity. Organic acid acetic acid (HAc), tannins (TA), and inorganic acid hydrochloric acid (HCl) were used to etch the UiO-66-NH skeleton, and only HCl can introduce reasonable protonation on UiO-66-NH without structural damage.

Developing efficient photocatalysts for visible-light-driven hydrogen evolution is crucial for sustainable energy conversion. Herein, a series of D-π-A-structured calixarene dyes (BFT-1COOH, BFT-2COOH, BFT-CNCOOH) with varied π-bridges and acceptor groups are molecularly engineered and integrated with Pt-loaded UiO-66-NH (Pt@U6N) to enhance photocatalytic hydrogen production. Systematic characterizations confirm the structural integrity of the composites and reveal reduced charge recombination due to hydrogen bonding between the dye carboxyl groups and U6N.

Chrysin is a common flavonoid compound with various pharmacological activities, which often exists in natural dietary sources such as propolis and honey. To selectively isolate and enrich chrysin from propolis, porous flower-like molecularly imprinted polymers nanomaterials were developed using a facile synthesis approach. The material was constructed by first decorating UiO-66 onto N-doped porous carbon flowers (NCFs), followed by coating the surface with a thin imprinting layer, yielding NCFs@UiO-66@MIPs.
