Specifically, they effectively remove methylene blue (MB) from water within 180 min at room temperature. The adsorption process primarily adheres to Lagergren pseudo-first-order kinetics, while the Langmuir isotherm model provides an excellent fit, indicating a very high monolayer adsorption capacity of 224.57 mg/g at ambient temperature.

A slight alteration in photophysical characteristics and the usual sensing behaviour of a hypochromic/hyperchromic or hypsochromic/bathochromic shift are the results of triazole schiff bases coordinating with the metal ions. In this review, we looked into the design, synthesis, ON/OFF &amp; OFF/ON Hg<sup>2+</sup> metal ion sensing mechanism, and practical application of the probes in an effort to merge the previously published triazole schiff baes-derived sensors. This review centres on the development of triazole schiff base as a fluorescent chemosensor for the study of Hg<sup>2+</sup> metal ions over the course of decades. In order to further explore the topic of triazole schiff base-based sensors for metal ion detection, we hope that this review will offer a basic framework.</div></div>","PeriodicalId":13599,"journal":{"name":"Inorganica Chimica Acta","volume":"587 ","pages":"Article 122789"},"PeriodicalIF":2.7,"publicationDate":"2025-06-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144335749","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}

Although traditional nanoparticles like metal and metal oxides have potent antibacterial properties, their excessive release of metal ions into human tissues as well as bacteria might have detrimental health effects. As a result, looking for alternative material becomes essential. Metal-organic frameworks (MOFs) are gaining interest, due to they combine two distinct areas—an organic part that exhibits intense and rapid bacterial activity and an inorganic part that contains broad-spectrum antibacterial agents. Additionally, MOFs' appropriate size enables them to either break through the bacterial membrane and degrade it or enter biofilm walls and start acting as an antibacterial agent. The ions for metal release, biocidal linkers, or even biocidal compounds enclosed in MOFs may be the source of MOFs' biological activity. MOFs are attractive prospects for biological and pharmaceutical applications because of these characteristics. Organic linkers of MOFs can be altered through solid-liquid reactions without compromising the characteristics of MOFs, the post-synthetic modification (PSM) technique is suited for bio active MOF synthesis because biocidal linkers are difficult to synthesis and can damaged before MOF formation. Here, 3-(2-hydroxyphenyl)-3-oxopropanal, methyl vinyl ketone, glyoxylic acid, and phthalaldehyde were used to synthesis and post-synthetically modify the metal organic framework based on indium ions (MIL-68-NH<sub>2</sub>), yielding MIL-68-HP, MIL-68-VK, MIL-68-GA, and MIL-68-PA in 40, 80, 87, and 92 %, respectively. The comprehensive study, involving synthesis, characterization, and detailed biological activity testing of the modified MOFs was investigated. The findings suggest that the PSM MOFs exhibit greater biological activity than commercial antibiotics against several tested microbial species. The obtained results showed the importance of MOFs used as an alternative to conventional antibiotics, and the PSM approach to tailor their properties was a valid strategy.</div></div>","PeriodicalId":13599,"journal":{"name":"Inorganica Chimica Acta","volume":"586 ","pages":"Article 122799"},"PeriodicalIF":2.7,"publicationDate":"2025-06-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144205244","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}
