摘要

Tetraphenylethene (TPE) and pyrene as typical aggregation induced emission (AIE) and aggregation caused emission quenching (ACQ) functional groups were utilized to design and synthesize water-soluble fluorescent molecules. Through a self-assembly process with cucurbituril hosts, a completed opposite fluorescence response was observed for TPE and pyrene based fluorescent molecules. The assembly processes were verified by ¹H NMR, UV–Vis, fluorescence spectroscopy. The mechanism was then studied and the aggregation-induced fluorescence change was concluded. These new host-guest supramolecular fluorescence systems can be used as fluorescence sensors or switches, expanding the application of fluorescence systems in biological imaging.
