摘　　要：Aggregation-induced emission-active 4-（3,4,5-bis（octyloxy）phenyl-9-anthracene acylhydrazone （AHP- T8） has been designed and synthesized, and the photo-responsive properties of organogel and xerogel irradiated by visible light were investigated systematically. AHP-T8 can form thermo-reversible gels in some of the tested solvents. The enhanced fluorescence emission has been observed after gelation although the dilute solution of AHP-T8 was almost non-fluorescent. When the organogel was exposed under visible light, the gel-sol phase transition occurred, and the corresponding morphology, fluorescence intensity, intermolecular hydrogen bonding and the structure all changed. In addition, the xerogel is more sensitive to visible light than that of organogel. The photoresponsive behaviour of AHP-T8 upon irradiation by visible light was demonstrated to be due to the E-Z isomerizations of -C=N-group. rather than the photodimerization of anthracene groupsAggregation-induced emission-active 4-（3,4,5-bis（octyloxy）phenyl-9-anthracene acylhydrazone （AHP- T8） has been designed and synthesized, and the photo-responsive properties of organogel and xerogel irradiated by visible light were investigated systematically.
