The HugZ/HutZ family has been shown to degrade heme in the presence of ascorbic acid. However, its inability to utilize canonical cytochrome P450 reductase has raised questions regarding its physiological role as a true heme oxygenase. PM0042 from Pasteurella multocida, a member of the HugZ/HutZ family, belongs to the pyridoxamine 5'-phosphate oxidase (PNPOx) family, which utilizes FMN as a cofac…

Molecular spintronics exploits the spin-dependent properties emerging at hybrid interfaces between magnetic substrates and molecular layers, offering promising routes toward novel spin-based devices. In this work, we present a comparative investigation of the structural, morphological, and electronic properties of iron(II) phthalocyanine (FePc) monolayers grown on bare Ni(111) and on graphenecove…

Photodynamic therapy (PDT) is a promising non-invasive cancer treatment, but its efficacy depends on photosensitizer performance. Porphyrin-based photosensitizers face challenges including poor water solubility, limited photodynamic effects, and weak near-infrared absorption. In this study, a new conjugated porphyrin (Por) was synthesized by coupling zinc porphyrin with pyridine through alkyne bo…

Melanin-like coatings derived from the spontaneous oxidation of catecholamines represent an attractive and versatile platform for surface functionalization strategies. However, the intrinsic broadband absorption of melanin-like polymers and their scavenging behavior toward reactive oxygen species often limit their use in applications requiring efficient photochemical outputs. Herein, we report a …

The five-coordinate iron(III) porphyrin complexes, (por)Fe(OSiMe 3 ) and (por)Fe(OCH 2 SiMe 3 ) (por = OEP, TPP, TpivPP) have been synthesized and characterized by spectroscopy. The magnetic susceptibility data obtained by the Evans method for the complexes indicate that they are high-spin or intermediate-spin species, depending on the axial ligand. The X-ray crystal structures of (OEP)Fe(OSiMe 3…

This study investigates the self-assembly kinetics of three structurally related sulfonatophenylporphyrins, 5,10,15,20-tetrakis(4-sulfonatophenyl)porphyrin (TPPS 4 ), 5,10,15-tris(4-sulfonatophenyl)-20-phenyl-porphyrin (TPPS 3 ) and 5,15-bis(4-sulfonatophenyl)-10,20-phenyl-porphyrin (t-TPPS2) into supramolecular J-aggregates in acidic aqueous solutions, using a series of inorganic acids. The aggr…

Symmetry-breaking charge transfer (SB-CT) has become a fundamental excited-state process through which symmetric molecular assemblies create polarized charge-separated states without permanent donor-acceptor asymmetry. By leveraging electronic degeneracy, vibronic coupling, and environmental stabilization, symmetry-breaking charge separation (SB-CS) enables directional charge separation with mini…

A new two-dimensional coordination polymer based on manganese(II) and 5,10,15,20-tetra- 3-pyridinyl-21H,23H-porphine, formulated as [Mn(TPyP)] n (1; TpyP = 5,10,15,20-tetra-3-pyridinyl- 21H,23H-porphine), was successfully synthesized under solvothermal conditions. Single-crystal X-ray diffraction revealed that the Mn[Formula: see text]. center adopts an octahedral geometry, coordinated by four eq…

To overcome challenges in cancer treatment, non-invasive photothermal therapy (PTT) and photodynamic therapy (PDT) hold significant promise. In this study, we designed a type of amino-modified SiO 2 -coated bismuth sulfide nanorods serving (Bi 2 S 3 ) and used amide reaction to couple with 3-(4- carboxyphenoxy) phthalocyanine zinc (ZnPc-COOH) to form a porous nanorods material, resulting in a Bi …

Difluorosilicon(IV) octapropylporphyrazine F 2 SiPzPr 8 was synthesized by reaction of metal-free octapropylporphyrazine with HSiCl 3 in refluxing pyridine, followed by axial fluorination with hydrofluoric acid. The molecular structure was determined by single-crystal X-ray diffraction, revealing a slight distortion of the porphyrazine macrocycle due to intermolecular interactions in the solid st…

Phthalocyanines and subphthalocyanines with novel peripheral functional groups are highly desirable for exploring their potential for widespread use across several research fields. Synthesis of the precursor phthalocyanines has been limited due to selectivity. A precursor, 4-bromo-5-nitro-phthalonitrile, is of interest due to its potential to undergo an S N Ar reaction. The S N Ar reaction, inher…

The hydrolysis reaction of PcNbCl 3 (Pc = phthalocyaninato) and PcNb(O i Pr) 3 produces the mu-oxo species [(PcNb) 2 (O)(μ-O) 2 ] (and some Nb 2 O 5 ), which was structurally characterized to reveal a dinuclear complex with two PcNb(V) units linked by two μ-oxo bridges; one of the Nb(V) centres has an additional terminal oxo ligand. [(PcNb) 2 (O)(μ-O) 2 ] has an overall butterfly-shaped structure…

Wound healing is a critical component of clinical care, directly influencing patient recovery, infection control, and overall health outcomes. However, effective wound management remains a significant challenge in modern medicine, as conventional therapies often fail to fully address infection control, inflammation, and tissue regeneration. Traditional approaches, including antibiotics, sterile d…

Porphyrins and phthalocyanines, endowed with highly conjugated π-systems and tunable coordination environments, have shown remarkable promise in photoelectrocatalysis and energy conversion.

[Formula: see text]-bridged [Formula: see text]-nitrido porphyrinoids are known for their catalytic properties in oxidation reactions. Many recent works have described how structural variations of such complexes (nature and substitution pattern of the porphyrinoid, and metalation) can modulate these properties. In this work, we assess the versatility of heteroleptic (phthalocyanine or porphyrin) …

Ferrocene is a versatile organic compound in organic electronics and biomedical applications owing to its oxidation stability and quick response to voltage. Nevertheless, ferrocene-appended organic compounds are seldom reported because of the incompatibility of design with redox materials, regioselectivity, intricate synthetic approaches, and poor yields. Hence, we have developed a corrole-linked…
