Abstract
Disclosed herein are compositions of a deep eutectic solvent with a host, such as a supramolecular host, and the use of the composition to form a composition comprising the host in complex with one or more guests. The deep eutectic solvent provides an alternative medium to the aqueous-based media that have been used in the art to date. Also disclosed are compositions of a deep eutectic solvent with a redox-active compound, such as a viologen compound, and the use of the composition, for example, in a smart window or for agricultural use, such as in an agricultural product.
