At the beginning of his youthful sixth decade, this work is dedicated to Prof. Dr. Fabio Doctorovich. He is distinctive in organometallic chemistry. During his successful career, he has been studying the reactivity and application of metalloporphyrins. Metalloporphyrins are organometallic complexes that exhibit, through synthetic modifications, the ability to tune their optical and electrochemical properties and their selectivity towards a particular molecule or ion. For this reason, they are systems extremely useful as electrochemical sensors to detect and quantify a wide variety of analytes with high selectivity, even in real samples such as food, water, biological fluids, or pharmaceutical compounds. This review presents an up-to-date list of reports in which metalloporphyrins are used as electrochemical sensors. In addition to compiling a comprehensive and up-to-date list of reported sensors that utilize metalloporphyrins, this work aims to provide an overview of currently available tools and techniques for the detection of various chemical species through similar approaches, which are constantly being developed.

“…Wang et al [ 201 ] developed an enzymatic sensor for the photoelectrochemical detection of hypoxanthine using a nanoscale porphyrin MOF (Al-TCPP(Zn)) modified with the xanthine oxidase enzyme. Al-TCPP(Zn) exhibited an O 2 -dependent cathodic photocurrent, and this signal could be used for photoelectrochemical detection.…”

The Chemistry and Applications of Metal–Organic Frameworks (MOFs) as Industrial Enzyme Immobilization Systems

Enzymatic biocatalysis is a sustainable technology. Enzymes are versatile and highly efficient biocatalysts, and have been widely employed due to their biodegradable nature. However, because the three-dimensional structure of these enzymes is predominantly maintained by weaker non-covalent interactions, external conditions, such as temperature and pH variations, as well as the presence of chemical compounds, can modify or even neutralize their biological activity. The enablement of this category of processes is the result of the several advances in the areas of molecular biology and biotechnology achieved over the past two decades. In this scenario, metal–organic frameworks (MOFs) are highlighted as efficient supports for enzyme immobilization. They can be used to ‘house’ a specific enzyme, providing it with protection from environmental influences. This review discusses MOFs as structures; emphasizes their synthesis strategies, properties, and applications; explores the existing methods of using immobilization processes of various enzymes; and lists their possible chemical modifications and combinations with other compounds to formulate the ideal supports for a given application.

“…8 The photophysical properties of MOFs have also been exploited to various photoelectrochemical (PEC) applications, such as PEC sensing and PEC catalysis. [17][18][19][20][21][22][23][24] Porphyrin-MOFs have been wildly used for singlet oxygen generation in photocatalysis resulting from the excellent photophysical properties of porphyrin ligand. 25 Li et al have reported a 2D Yb-porphyrin nanosheet for high-performance photocatalytic synthesis of juglone.…”

Synthesis of Ln‐porphyrin aerogels with abundant porosity and novel photophysical properties for luminescent sensing and photocatalysis should have significant importance. In this paper, a multifunctional Tb‐porphyrin aerogel was synthesized using agarose as a building block for ratiometric fluorescent Cu(II) sensing and photocatalytic degradation of rhodamine B. Specially, Tb‐porphyrin particles were introduced into agarose aerogel to give the Tb‐porphyrin aerogel with porous structure. Tb‐porphyrin aerogel shows an excellent sensing performance toward Cu(II) resulting from the self‐referencing mechanism and the porous structure. The fluorescent response exhibits a linear range from 1 to 200 μM (R2 = 0.990), and the limit of detection is 50 nM (S/N = 3). Such a ratiometric fluorescent sensor shows excellent long‐term stability and selectivity. Furthermore, the Tb‐porphyrin aerogel was used for photocatalytic degradation of rhodamine B, exhibiting a more efficient activity compared with the Tb‐porphyrin particle. This research should open up a new avenue to develop Ln‐porphyrin aerogel‐based material for ratiometric fluorescent sensing and photocatalysis.
