Porphyrin compounds take on vibrant shades of color thanks to their π electrons. The network of double bonds—also known as a ...

A huge molecular wheel has set a new record as the largest aromatic ring (Nat. Chem. 2020, DOI: 10.1038/s41557-019-0398-3). The molecule could be a step toward making even bigger rings that serve ...

The new catalyst is created using molecular self-assembly. During this process, a vial filled with molecules called cobalt porphyrins (vial on the left) is mixed with a vial of ruthenium “clips” (vial ...

How porphyrin may enhance graphene Date: January 5, 2017 Source: Plataforma SINC Summary: Porphyrins, the same molecules that convey oxygen in haemoglobin and absorb light during photosynthesis ...

These porphyrins accumulate in the skin and other organs before being excreted in feces and urine (which may turn a port-wine color). Exposed to light, the porphyrins can turn caustic and destroy ...

Porphyrin-based nanosheet filters capture nanoparticles as small as viruses (~100 nm) while maintaining high air flow. The filter, constructed from ordered porphyrin meshes on nanofiber-modified ...

Two-dimensional porphyrin-based COFs show great promise for photocatalytic CO2 reduction, yet their π-π stacking often impedes active site exposure and charge transfer. Researchers developed a ...

THE average physician confronted with the subject of porphyrin metabolism pictures either a bewilderingly complex group of strange pigments obtained from stools and ...

Porphyrin metabolism was found to be abnormal in 8 patients with polymorphic photodermatitis. All the clinical morphologic variants of polymorphic photodermatitis were present in this group of ...
