“…[H 2 (TMtPP)] showed four absorptions (Q bands) at 522, 555, 604 and 650 nm and an intense absorption (Soret band) at 424 nm, Table 1. The four peaks are typical of freebase porphyrins [24] . [Co II (TMtPP)] showed one Q band at 544 nm, and Soret band at 419 nm.…”

In this work, we present Zn, CoII, and MnIII metalated meso‐tetra‐[4‐(methylthio) phenyl] porphyrin ([Zn(TMtPP)], [CoII(TMtPP], and [MnIII(TMtPP)Cl]) as electrocatalysts and photoelectrocatalysts for electrochemical detection and photoelectrocatalytic degradation of pentachlorophenol (PCP). The complexes were characterized using UV‐visible spectroscopy, mass spectroscopy, and elemental analysis. Proton nuclear magnetic resonance (1H NMR) studies were only conducted for the Zn derivative. The electrochemical detection of PCP was carried out using cyclic voltammetry and chronoamperometry. [CoII(TMtPP)] showed better detection limit. For photoelectrocatalytic (PEC) degradation studies of PCP, linear sweep voltammetry and UV‐visible spectra were employed. [Zn(TMtPP)] showed better removal efficiency. The main species responsible for the PEC degradation were found to be superoxide radicals (⋅O2) and electron holes (h+).

“…The design and the synthesis of metal containing macrocyclic compounds is a field of great interest [1]. Synthetic macrocyclic complexes can mimic some naturally occurring macrocycles due to their resemblance with natural macrocycles, such as metalloproteins and metalloenzymes [2,3]. Macrocyclic complexes have applications in the field of biometallic activation and catalysis [4], pharmaceuticals [5] and pigments and dyes [6].…”

Three novel organotellurium decorated 10-membered tetraazamacrocyclic complexes of Co(II) were synthesized using template condensation of 1,1-diiodo-1-telluracyclopentane, 1,1-diodo-2-methyl-1-telluracyclopentane and 1,1-diiodo-1,1-diethyltellurium(IV) with 1,2-diaminopropane and cobalt dichloride hexahydrate in dry methanol in 2:2:1 molar ratio. The characterization of the synthesized cobalt(II) complexes was carried out using elemental analysis, spectroscopic studies (IR, proton NMR & proton decoupled carbon NMR) and molar conductance measurements. The results of these studies suggested that the complexes may be formulated as [CoLCl2] where L = {C4H8Te-(NHCH2CH(CH3)NH)}2, {C4H7(CH3)Te(NHCH2CH(CH3)NH)}2 and {(C2H5)2Te(NHCH2CH(CH3)NH)}2. The synthesized complexes were also screened for antimicrobial activity using broth microdilution and agar disc diffusion methods.

“…Here, we mention that porphyrin-based macrocycles benefiting from their more excellent optical properties than other macrocycles are receiving growing attention in biomedical applications. For readers who would like to know more about porphyrin-based macrocycles and their biomedical applications, the following articles are recommended. − In detail, chemical structure design, self-assembly behavior, and the advantages and potential disadvantages of every system are comprehensively illuminated first. After that, the performances of PBAs and their self-assembly nanomaterials in disease treatments and diagnoses are discussed according to Figure .…”

Porphyrins have been vastly explored and applied in many cutting-edge fields with plenty of encouraging achievements because of their excellent properties. As important derivatives of porphyrins, porphyrin-based amphiphiles (PBAs) not only maintain the advanced properties of porphyrins (catalysis, imaging, and energy transfer) but also possess self-assembly and encapsulation capability in aqueous solution. Accordingly, PBAs and their self-assembles have had important roles in diagnosing and treating tumors and inflammation lesions in vivo, but not limited to these. In this article, we introduce the research progress of PBAs, including their constitution, structure design strategies, and performances in tumor and inflammation lesion diagnosis and treatments. On that basis, the defects of synthesized PBAs during their application and the possible effective strategies to overcome the limitations are also proposed. Finally, perspectives on PBAs exploration are updated based on our knowledge. We hope this review will bring researchers from various domains insights about PBAs.
