The detection of metal ions is crucial in biological, environmental, and industrial fields, as metal ions such as Cu²⁺ play essential physiological roles but can be toxic at elevated concentrations. Triazole-based chemosensors exhibit excellent metal-binding properties, leading to changes in fluorescence, redox potential, and colorimetric responses, making them effective tools for selective and sensitive metal ion detection. Recent research has focused on the development of triazole-based fluorescent chemosensors for Cu²⁺ ions recognition, exploring structural modifications, sensing mechanisms, and practical applications. These chemosensors offer advantages such as high promising candidates for real-time detection in biological and environmental monitoring. This review highlights advancements in triazole-based fluorescent chemosensors for Cu²⁺ ion detection from 2013 to 2023, summarizing key developments and their potential applications.

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}
