This study presents the rational design of biosourced mixed-metal cluster-based MOFs, Fe₂M-fumarate (M = Cu, Zn, Mn), and isostructural with MIL-88A (Fe). The frameworks serve a dual purpose: as degradable micronutrient fertilizers that enable controlled metal release through the slow breakdown of secondary building units and as reservoirs for atmospheric moisture due to their water-adsorption characteristics. Physicochemical characterization confirmed the successful formation of homogeneous mixed-metal clusters, yielding spindle-shaped crystallites with distinct porosity profiles. Notably, the Fe₂Cu–MIL-88A analogue exhibited a unique “breathing” behavior, achieving a remarkable water vapor uptake of ~630 mg g⁻¹, significantly outperforming the Zn and Mn analogues. In contrast to the rapid dissolution characteristic of conventional salts, in vitro release assays revealed a biphasic profile, with a gradual initial release of Cu, Zn, or Mn, followed by a more sustained release of Fe, driven by hydrolytic matrix degradation. Kinetic modeling indicated that the Weibull model (<i>R</i>² ≤ 0.98) best describes this complex mechanism, which combines erosion and diffusion. The release profiles can be tuned by varying the secondary metal within the trimeric cluster, illustrating the versatility of this approach. These findings position Fe₂M–fumarate nanorods as a promising platform for moisture-responsive, sustained-release micronutrient delivery in agricultural environments.</p>\u0000 </div>","PeriodicalId":8344,"journal":{"name":"Applied Organometallic Chemistry","volume":"40 8","pages":""},"PeriodicalIF":4.3,"publicationDate":"2026-07-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148615622","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The sensing performance is based on the interactions between the APTMS-QDs@MOF and nitrate ions. The amine–Zn interaction and electrostatic interaction between negatively charged MOF and positively charged APTMS-QDs result in the quenching of APTMS-QDs due to an electron transfer process, along with the formation of the flower-like morphology of APTMS-QDs@MOF. When nitrate ions were introduced into the APTMS-QDs@MOF system, the quenching effect was reduced, resulting in a noticeable recovery of fluorescence.
