Construction of a Novel Photoresponsive Supramolecular Fluorescent Hydrogel through Host-Guest Interaction between beta-Cyclodextrin and Azobenzene

摘要

abstract_textpIn the present work, we constructed a novel photoresponsive supramolecular fluorescent hydrogel through host-guest interaction between beta-cyclodextrin group in polymer 1 and azobenzene group in polymer 2. Under different external irradiations, the fluorescent hydrogel exhibited different intensities to the photo-isomerisation of azobenzene. Light is an ideal stimulus because of its simple operation and non-introduction of additional impurities. Therefore, this photoresponsive supramolecular hydrogel can serve as an excellent strategy for designing more practical materials./p/abstract_text
