Abstract

A simple and convenient method to prepare acid-responsive microcapsules by using functionalized single-walled carbon nanotubes and ytterbium triflate has been developed. Fluorescence active compounds were “pre-loaded” or “post-loaded” in the microcapsules and released later in acidic medium. An interesting “zip–unzip” phenomenon was observed while filming the action of acid on microcapsules under a microscope.
