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 ...

Researchers have incorporated molecules of porphyrin CO2 catalysts into the sponge-like crystals of covalent organic frameworks (COFs) to create a molecular system that not only absorbs carbon dioxide ...

Several clinically approved nanocarriers such as liposomes have been developed to improve the biodistribution and anticancer efficacy of various drugs 1,2. However, delivery is hampered by ...

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 ...

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 ...

(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 ...
