(Nanowerk News) Ethers – simple organic molecules in which an oxygen atom bridges two carbon atoms – are the chemical building blocks of commonplace products including many solvents, propellants, ...

This study is led by professor Yong Cui (School of Chemistry and Chemical Engineering, Shanghai Jiao Tong University, China). The authors demonstrate that incorporating chiral crown ethers into stable ...

Crown ethers were discovered in 1967. They were then modified by adding a metal-containing unit creating metallacrown ethers. These metallacrown ethers have been the subject of intensive research.

Crown ether complexes, characterised by their macrocyclic structures and ability to selectively encapsulate metal cations, have long been a focus of supramolecular chemistry. Their unique coordination ...

A polysilsesquioxane with a bis(2-methoxyethyl)amide group and 15-crown-5-ether ring (MCPSQ) was newly prepared by the co-condensation of silane coupling reagents, which were obtained from ...

HSINCHU, Taiwan--(BUSINESS WIRE)--In a revolutionary advance in clean energy technology, a research team led by Professor Ho-Hsiu Chou from the Department of Chemical Engineering at National Tsing Hua ...

Scientists have discovered a way to dramatically increase the selectivity and binding strength of crown ethers by incorporating them within a rigid framework of graphene. Strong, specific ...
