An overview on AIEgen‐decorated porphyrins: Current status and applications

open access: yesAggregate, 2023
One of the major obstacles of porphyrins is the aggregation‐caused quenching (ACQ) of photoluminescence due to the strong intermolecular π–π interaction of the planar porphyrin core in the solid state.

Mechanisms of Phototoxic Effects of Cationic Porphyrins on Human Cells In Vitro

open access: yesMolecules, 2023
The toxic effects of four cationic porphyrins on various human cells were studied in vitro. It was found that, under dark conditions, porphyrins are almost nontoxic, while, under the action of light, the toxic effect was observed starting from nanomolar ...

Possible therapeutic targets and promising drugs based on unsymmetrical hetaryl-substituted porphyrins to combat SARS-CoV-2

open access: yesJournal of Pharmaceutical Analysis, 2021
Coronavirus disease 2019 is a serious disease that causes acute respiratory syndrome and negatively affects the central nervous system. Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) crosses the blood-brain barrier due to the spike (S ...

Porphyrin Wheels [PDF]

open access: yesJournal of the American Chemical Society, 1996
A simple method to prepare porphyrin 'wheels' on a micrometer scale is described. It is possible to arrange several types of porphyrin derivatives, including Protoporphyrin IX and Chlorophyll-a, in the form of rings using this method. A mechanism for the formation of these types of assemblies is proposed that is based on the generation of '2D-gas ...

Geospatial Synthesis of Biogeochemical Attributions of Porphyrins to Oil Pollution in Marine Sediments of the Gulf of México

open access: yesGeosciences, 2022
Porphyrins are highly persistent in the environment and represent a helpful biogeochemical attribute to assess the spatial distribution of the effects of oil spills on ecosystems and their resilience.

Air oxidation of the kerogen/asphaltene vanadyl porphyrins: an electron spin resonance study [PDF]

open access: yesJournal of the Serbian Chemical Society, 2000
The thermal behavior of vanadyl porphyrins was studied by electron spin resonance during heating of kerogens, isolated from the La Luna (Venezuela) and Serpiano (Switzerland) bituminous rocks, at 25°C for 1 to 20 days in the presence of air.

Functionalization of Porphyrins Using Metal-Catalyzed C–H Activation

open access: yesInorganics, 2022
The review is devoted to the C–H functionalization of porphyrins. Porphyrins exhibit the properties of organic semiconductors, light energy converters, chemical and electrochemical catalysts, and photocatalysts.

Anthracene‐Porphyrin Nanoribbons

open access: yesAngewandte Chemie International Edition, 2023
Abstract π‐Conjugated nanoribbons attract interest because of their unusual electronic structures and charge‐transport behavior. Here, we report the synthesis of a series of fully edge‐fused porphyrin‐anthracene oligomeric ribbons (dimer and trimer), together with a computational study of the corresponding ...

Cellular Localization of Selected Porphyrins and Their Effect on the In Vitro Motility of Human Colon Tumors and Normal Cells

open access: yesMolecules, 2023
Standard therapies for colorectal cancer cannot eliminate or sufficiently reduce the metastasis process. Photodynamic therapy (PDT) may be an alternative to minimizing this problem.
