Encapsulation within a coordination cage modulates the reactivity of redox-active dyes

Abstract

Water-soluble nanocontainers that can encapsulate and modulate the properties of synthetic fluorescent probes could expand the versatility of such probes in biologically relevant environments. Here, the authors encapsulate the resazurin/resorufin redox pair within a flexible palladium-based coordination cage and find that confinement drastically alters the optical and redox properties of the two dyes.
