“…Metal–organic frameworks (MOFs) are porous materials composed of central metal ions or metal ion clusters and organic ligands. They have attracted great attention in recent decades for their exceptional properties, such as high surface areas, tunable porosity, and functional surfaces. − At present, MOFs have been widely applied in the fields of absorption, , separation, sensors, , catalysis, drug delivery, , and therapy. , Recently, MOFs have also shown great potential in agricultural development. , For example, MOFs can be applied to environmental remediation (removal of agrochemicals by adsorption or catalytic degradation), , environmental pollutant monitoring, and plant drug delivery . With the widespread application of MOFs, there is a pressing need to evaluate their environmental impacts.…”

With the increasing use of metal−organic frameworks (MOFs), they will inevitably enter the environment intentionally or unintentionally. However, the effects of MOFs on plant growth are poorly understood. Here, we investigated the effects of exposure of the rhizosphere to MOFs on plant growth. MIL-101(Cr) was selected as a research model due to its commercial availability and wide use. Soybean plants at the twoleaf stage were subjected to various durations (1−7 days) and concentrations (0−1000 mg/L) of exposure in hydroculture with a control group treated with ultrapure water. We found that MIL-101(Cr) had a positive effect on soybean growth at a lower dose (i.e., 200 mg/L); however, at higher doses (i.e., 500 and 1000 mg/ L), it exhibited significant toxicity to plant growth, which is evidenced by leaf damage. To investigate the mechanism of this effect, we used Cr as an indicator to quantify, track, and image MIL-101(Cr) in the plant with laser ablation inductively coupled plasma mass spectrometry (LA-ICP-MS). Results indicated that MIL-101(Cr) primarily accumulated in the cortex of roots (up to 40 times higher than that in stems), with limited translocation to stems and negligible presence in leaves and cotyledons. In addition, metabolomic analysis of soybeans indicated that low-dose MIL-101(Cr) could increase the sucrose content of soybean roots to promote plant growth, while a high dose could induce lipid oxidation in roots. This study provides valuable insights into the ecological toxicology of MOFs and underscores the importance of assessing their environmental impact for sustainable agricultural practices.

Ratiometric fluorescent sensing based on dual-emitting fluorescent coordination polymers (FL-CPs) has attracted intense attention due to their sensing accuracy and easy visualization when compared with sensing relying solely on monochromatic FL-CPs. In this work, a series of rare-earth metal-based CPs, formuled as [(CH3)2NH2][Ln(bpdc)2] (Ln3+ = Y3+, Eu3+ and Tb3+, H2bpdc = biphenyl-4,4′-dicarboxylic acid), are presented, which show dual emission aroused from the Ln3+ ions and the inefficient intermolecular energy transfer from ligands to Ln3+ metals. For clarity, the as-made Ln-CPs are named Eu-bpdc, Tb-bpdc, and Y-bpdc based on the corresponding Ln3+. Notably, Eu-bpdc, presented as an example, could be used as FL sensing material ratiometric to Fe3+ ions. The ratio of FL intensity of Eu3+ ions to bpdc2− ligands (I415/I615) showed a good linear relationship with the concentrations of Fe3+ ions. Moreover, the detection process could be visibly monitored through a change from purple to blue when Eu-bpdc was used as an FL proble. This work provides a good example for exploring visibly ratiometric sensors based on FL-CPs.
