Crown ether cyclic molecules have a unique structure with a central ring that can hold a variety of atoms, molecules, and ions. Prof. Yamada explains, "Previously, we found that crown ether cyclic ...

Link them together in large molecular rings and they become scientific royalty -- crown ether molecules, whose development led in large part to the 1987 Nobel Prize in chemistry.

Molecules from the solvent environment that at first glance seem to be uninvolved can be essential for chemical reactions. This has been shown by researchers studying the formation of an ether in ...

The complex of ammonium-linked ferrocene (Fc-amm) and crown ether is assembled on a Cu(111) surface, and its sliding motion is activated by hole injection into the ferrocene group using scanning ...
