Efficient enhancement of fluorescence emission via TPE functionalized cationic pillar[5]arene-based host-guest recognition-mediated supramolecular self-assembly

摘要

A tetraphenylethene (TPE) functionalized cationic pillarplarene (CWP5-TPE) was successfully synthesized, and the intramolecular rotation of the TPE motif was restricted via cationic pillar[5jarene-based host guest recognition-mediated supramolecular self-assembly in water, resulting in the efficient enhancement of fluorescence emission based on the aggregation induced emission (AIE) mechanism. CWP5-TPE self-assembled into nanoribbons while the host guest inclusion complex formed into supramolecular amphiphile nanoparticles in water. (C) 2017 Elsevier Ltd. All rights reserved.
