Abstract Photochromic materials have attracted great attention due to their unique photoresponsive behavior and prospective applications as intelligent materials. In this work, a fluorescent molecule TPE-4DCS with two aggregation-induced emission (AIE) groups, tetraphenylethylene and cyanostilbene, was synthesized and its photophysical properties were systematically investigated. The results of the spectra experiments showed that TPE-4DCS has the typical AIE properties. Moreover, due to the reversible Z/E isomerization of the cyanostilbene unit, the fluorescence intensity of the TPE-4DCS solution gradually decreases under 365 nm UV irradiation and shows a spectral blue shift, while the fluorescence can be recovered under 254 nm UV irradiation. Therefore, TPE-4DCS is a new material with potential application in fluorescence sensing and other fields.
