Adenosine triphosphate (ATP), the universal energy currency of living systems, represents a valuable analytical target in sensing technology. However, discriminating ATP from its closely related analogues (ADP, AMP) remains a challenge. Herein, we report the synthesis of two arene ruthenium metalla-rectangles incorporating urea-based units. These water-stable assemblies are obtained from the dinuclear complex [Ru2(p-cymene)2{bis(2-hydroxyethyl)oxamidate}Cl2] and the bipyridyl connectors 1,1′-(1,4-phenylene)bis{3-(pyridin-4-yl)urea} (PPU) and 1,1′-(naphthalene-1,5-diyl)bis{3-(pyridin-4-yl)urea} (NPU) in the presence of silver triflate. Both metalla-rectangles are isolated as triflate salts, with the formula [Ru4(p-cymene)4{bis(2-hydroxyethyl)oxamidate}2(PPU)2](CF3SO3)4 (MRPPU) and [Ru4(p-cymene)4{bis(2-hydroxyethyl)ethanediamide}2(NPU)2](CF3SO3)4 (MRNPU), respectively. Both metalla-rectangles can interact with fluorescein (FLU) to form weakly-fluorescent host-guest systems, resulting in discrete fluorescent indicator displacement assays (FIDA). The MRPPU rectangle shows in buffered aqueous solution a selective ATP recognition over purine nucleotides, as opposed to MRNPU, with an affinity of 2.4 × 104 M-1 and a detection limit of 22.0 μM. The dissimilar response of these two metalla-rectangles is rationalized from their molecular design, suggesting distinct binding interactions with ATP.</div></div>","PeriodicalId":374,"journal":{"name":"Journal of Organometallic Chemistry","volume":"1048 ","pages":"Article 124029"},"PeriodicalIF":2.1,"publicationDate":"2026-03-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"146037032","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To overcome this challenge without compromising catalytic efficiency, we report a facile ionic self-assembly strategy to construct a new class of polynuclear ferrocenyl-carboxylate complexes. By electrostatically coupling (ferrocenylmethyl)trimethylammonium cations with carboxylate anions of varying valency (acetate, oxalate, citrate, and EDTA), four distinct ionic catalysts (IFC-1 to IFC-4) were synthesized. Among these, the tetranuclear complex IFC-4 exhibited the most promising properties. Electrochemical analysis revealed that IFC-4 possesses a unique redox behavior with a high oxidation potential (0.81 V), contributing to its stability. When applied to ammonium perchlorate (AP), IFC-4 (5 wt%) demonstrated superior catalytic activity, reducing the high-temperature decomposition peak by 79 °C and increasing the decomposition rate constant by 12-fold compared to pure AP. Crucially, accelerated aging tests confirmed that IFC-4 exhibits exceptional anti-migration performance, with a diffusion coefficient of 8.70 × 10⁻¹¹ cm² s⁻¹—approximately two orders of magnitude lower than that of commercial catocene (2.38 × 10⁻⁹ cm² s⁻¹). This drastic reduction in mobility is attributed to the synergistic effects of increased molecular weight, structural rigidity, and strong electrostatic anchoring within the propellant binder network. These findings establish ionic self-assembly as a robust pathway for engineering high-performance, migration-resistant energetic catalysts.</div></div>","PeriodicalId":374,"journal":{"name":"Journal of Organometallic Chemistry","volume":"1048 ","pages":"Article 124057"},"PeriodicalIF":2.1,"publicationDate":"2026-03-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"146171219","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
