Abstract

Abstract:

Fluorescent microcapsules based on coordination supramolecular polymers of rare earth metal ions were prepared via a layer-by-layer technique that used electrostatic interaction. The holes in the capsule walls were very small, which reduced leakage of small molecular payloads. The capsules remained intact at salt concentrations as high as 500 mmol·L^-1, which shows they have potential in practical applications. Multicolored capsules were obtained simply using a mixture of terbium and europium ions.

Key words: Layer-by-layer assembly, Fluorescent capsule, Metallic coordination supramolecular polymer
