Langmuir monolayers and Langmuir–Blodgett multilayers containing macrocyclic ionophores

Macrocyclic ionophores in thin films are of interest for sensors or novel ionophotoswitching devices. Continuing work on floating monolayers and Langmuir–Blodgett multilayers of macrocyclic ionophores—such as crown ether ionophores, cyclodextrins and valinomycin—is reviewed. The figure shows a schematic representation of the complex of valinomycin (a biopolymer based on a 36‐membered ring) with potassium. magnified image
