“…Over the past two decades, nanomaterials have drawn the attention of material chemistry researchers due to their extensive applicability in various fields, including catalysis, solar energy conversion and storage, molecular recognition, sensing, and cancer treatment [1][2][3][4][5]. These compounds have been widely used to improve the properties of materials, which include high electrical conductivity, excellent optoelectronics, and corrosion resistance [6][7][8]. There is no doubt that these highly ordered nanostructures exhibit tremendously useful features, including large surface areas, various chemical and physical properties, as well as high thermal stability, compared to their parent components.…”

A series of porphyrin triads (1–6), based on the reaction of trans-dihydroxo-[5,15-bis(3-pyridyl)-10,20-bis(phenyl)porphyrinato]tin(IV) (SnP) with six different phenoxy Zn(II)-porphyrins (ZnLn), was synthesized. The cooperative metal–ligand coordination of 3-pyridyl nitrogens in the SnP with the phenoxy Zn(II)-porphyrins, followed by the self-assembly process, leads to the formation of nanostructures. The red-shifts and remarkable broadening of the absorption bands in the UV–vis spectra for the triads in CHCl3 indicate that nanoaggregates may be produced in the self-assembly process of these triads. The emission intensities of the triads were also significantly reduced due to the aggregation. Microscopic analyses of the nanostructures of the triads reveal differences due to the different substituents on the axial Zn(II)-porphyrin moieties. All these nanomaterials exhibited efficient photocatalytic performances in the degradation of rhodamine B (RhB) dye under visible light irradiation, and the degradation efficiencies of RhB in aqueous solution were observed to be 72~95% within 4 h. In addition, the efficiency of the catalyst was not impaired, showing excellent recyclability even after being applied for the degradation of RhB in up to five cycles.

“…[8,11,23,25,30] Several researchers have focused on the advances in GO and rGO preparation and applications. [31][32][33][34][35][36][37] The oxygenated groups of GO and, to a lower extent, those of rGO, can significantly improve performance when these materials are used as (bio)electrochemical sensors. [4] Therefore, herein, we provide an overview of the use of GO and rGO as electrochemical sensing platforms for medical and environmental applications, and the relationships between the structural properties of these materials and their modification with different molecules to introduce different functionalities.…”

Owing to their versatility and unique characteristics, graphene‐based materials have been used extensively for the development of electrochemical sensors and biosensors. The key to the maximum potential of these materials is the understanding of the role their structure plays in their modification processes. Herein, we summarize some structural characteristics of graphene oxide (GO) and reduced graphene oxide (rGO) and explore different surface modification methods for electrochemical sensing applications. surveyed the most recent applications of these materials as (bio)sensors, particularly for environmental monitoring and health‐related applications, such as quantification of biomarkers and metabolites and detection of cancer cells. The low detection limits, selectivity toward target molecules, and robustness of GO‐ and rGO‐based electrodes render them critical materials for the preparation of sensors for routine analysis and monitoring.
