crown ether

noun

1. chem a type of cyclic ether consisting of a ring of carbon and oxygen atoms, with two or more carbon atoms between each oxygen atom

Example Sentences

Additionally, unlike the usual behavior of crown ether molecules in solution, these molecules did not trap the metal atom at the center of the crown ring.

From Science Daily

In summary, the team successfully demonstrated the growth of cobalt NCs by exploiting the trapping potential of two-dimensional crown ether molecules on a copper surface.

From Science Daily

The chemical behavior of the crown ether molecules deviated from typical interactions observed in solution, by trapping cobalt atoms at the edge, and not the center.

From Science Daily

To achieve high solubility in the bulky solvent, the team functionalised each cage with six crown ether groups.

From Scientific American

‘Usually, long or branched alky chains are employed to increase the solubility or lower the melting point of a larger molecule, but linear alkyl chains can penetrate into the cavities of adjacent molecules, resulting in non-porous liquids. James et al used a clever trick to solve this problem: they combined a porous crown-ether-decorated molecule with a crown ether.’
