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 as a ...

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 ...

Organic chemistry, the chemistry of carbon compounds, is the basis of all life on Earth. However, metals also play a key role in many biochemical processes. When it comes to "marrying" large, heavy ...

(a) Schematic of the liquid cell for XAS analysis of metal porphyrin complexes in aqueous solutions. XAS spectra of the central metals were obtained at the Fe or Co L 2,3-edge and those of ligands ...

Recently, Rui Cao and Weiqiang Zhang of Shaanxi Normal University, Shunichi Fukuzumi and Wonwoo Nam of Ewha Womans University, and others published a letter entitled “A cobalt(II) porphyrin with a ...
