Porphyrin complexes remain at the forefront of coordination chemistry owing to their versatile structure and rich electronic properties. These macrocyclic compounds, characterised by a central cavity ...

Heme is a coordination complex consisting of a porphyrin ring surrounding a single ferrous (Fe 2+) or ferric (Fe 3+) ion, able to bond with diatomic oxygen and transport it around the body. Four heme ...

Porphyrin compounds take on vibrant shades of color thanks to their π electrons. The network of double bonds—also known as a π-conjugated aromatic system—going around 5,10,15,20-tetraphenylporphyrin ...

Reserachers report a porphyrin polymer that can capture precious metals from chemically digested electronic waste. Used circuit boards, screens, and other electronic waste contain precious metals, ...
