Color-tunable luminescent materials via a CB[8]-based supramolecular assembly strategy

Abstract

Fabricating color-tunable organic luminescent materials through a supramolecular host–guest strategy has attracted considerable attention recently. Herein, a series of color-tunable emissive materials consisting of small organic molecules, cucurbit[8]uril (CB[8]), and their host–guest complexes were developed. Fluorescent wavelength can be reversibly regulated by controlling the concentration of CB[8] in aqueous solution. Such properties exhibited promising applications for smart luminescent materials.
