Porphyrins as Catalysts in Scalable Organic Reactions
Catalysis is a topic of continuous interest since it was discovered in chemistry centuries ago. Aiming at the advance of reactions for efficient processes, a number of approaches have been developed over the last 180 years, and more recently, porphyrins ...

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

Functionalization of Porphyrins Using Metal-Catalyzed C–H Activation
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.

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

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 ...

Thiol regulation by Mn porphyrins, commonly known as SOD mimics
Superoxide dismutases play an important role in human health and disease. Three decades of effort have gone into synthesizing SOD mimics for clinical use. The result is the Mn porphyrins which have SOD-like activity.
