Therefore, the accurate quantification of TC concentrations and assessment of its environmental impact are critical steps in evaluating pollution risks. However, the development of portable and practical methods for detecting tetracycline (TC) in aquatic environments remains a significant challenge. Herein, a samarium-based metal-organic framework (Sm-MOF) was constructed through a solvothermal approach, utilizing pyromellitic acid (H<sub>4</sub>BTEC) and nicotinic acid (HNTCA) as dual ligands. The resulting 3D framework was stabilized through a synergistic interplay of coordination bonds and hydrogen bonding interactions, endowing the structure with exceptional stability for functional applications. Notably, the Sm-MOF exhibited a distinct fluorescence quenching response upon selective recognition of TC, even in the presence of multiple interfering species, highlighting its potential for precise detection in complex environments. The experimental results demonstrated that the Sm-MOF exhibited significant potential as a highly effective sensor material for TC detection, characterized by its rapid response time, exceptional anti-interference performance, and excellent recyclability. Moreover, DFT calculations revealed that the fluorescence quenching mechanism of Sm-MOF for TC was primarily governed by fluorescence resonance energy transfer (FRET) and photoinduced electron transfer (PET).</div></div>","PeriodicalId":13599,"journal":{"name":"Inorganica Chimica Acta","volume":"581 ","pages":"Article 122624"},"PeriodicalIF":2.7,"publicationDate":"2025-03-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143577753","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}

This wide absorption window makes them suitable candidates for many different applications dealing with light interaction, as need in the new emerging solar cells technologies, in the non-linear optics field and in medical applications such as bioimaging and photodynamic therapy (PDT). By introducing substituents at the <em>meso</em>- or <em>beta</em>-pyrrole position, the porphyrin absorption spectrum can be modified according to the requirements of the different application fields. One of the most effective way to deep affect the UV–vis spectrum of porphyrins is to extend the π-electron system of the tetrapyrrole ring. This can be achieved by introducing triple or double C<img>C bonds directly connected at <em>meso</em>- or <em>beta</em>-position. However, while the introduction of a simple triple bond and, more in general, alkynes exploiting Sonogashira reaction is widely used in porphyrin chemistry affording very high yields, the introduction of a double bond or alkenyl compounds with a well-defined stereochemistry through classical reactions or palladium-catalyzed cross-coupling reactions still remains problematic in terms of hard reaction conditions, excess of alkene reagents, by-products formation. In this review we want to report the synthetic methods described in the literature for obtaining <em>meso</em>- and <em>beta</em>-functionalized porphyrins by means of coupling alkenyl derivatives with porphyrins and metalloporphyrins, thorough the use of the Heck cross-coupling reaction that, if on one hand, is well consolidated with canonical reagents (e.g. with simple aryl-halides, either bromo- or iodo-, or even aryltriflates) on the other side it can be very tricky when <em>meso-</em> or- <em>beta-</em>brominated porphyrin are used. Nevertheless the Heck cross-coupling reaction still remains one of the most versatile synthetic methodology to modify the porphyrin core and, consequently, the optical properties of the tetrapyrrole macrocycle. We will briefly discuss which results can be obtained when bromoporphyins are used as starting aryl-halide and show the last achievements of such coupling by the use of the modern palladium transmetallation reactions.</div></div>","PeriodicalId":13599,"journal":{"name":"Inorganica Chimica Acta","volume":"581 ","pages":"Article 122598"},"PeriodicalIF":2.7,"publicationDate":"2025-02-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143535405","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}

Further, the optimized molecular structures were derived from B3LYP/6-311G(d,p) and the results were rationalized with the support of TD-DFT calculations. Afterwards, synthesis of a substituted five membered heterocyclic compounds were carried out in an ethanolic solution of benzil/9,10-phenanthrenequinone, substituted aldehydes and ammonium acetate (nitrogen source) as a substrate while employing aforementioned all four aluminium(III) complexes as catalyst. These organic compounds were characterized by spectral tools like NMR (<sup>1</sup>H &amp; <sup>13</sup>C) and FTIR. Furthermore, nitro derivative <strong>6c’</strong> was validated by SC-XRD that appeared as monoclinic system with space group of <em>P</em>2<sub>1</sub>/n. This study is the foremost approach to utilize aluminium(III) complexes as catalyst for the condensation reaction of 2,4,5-triarylimidazole and phenanthro[9,10-<em>d</em>]imidazole where obtained organic derivatives were synthesized in 83–95 % yields.</div></div>","PeriodicalId":13599,"journal":{"name":"Inorganica Chimica Acta","volume":"580 ","pages":"Article 122596"},"PeriodicalIF":2.7,"publicationDate":"2025-02-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143510949","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}
