摘要：

A novel approach to stimuli-responsive gel termed the "keto-enol tautomerization''-based response mechanism was proposed. By tautomerization, vinyl ketone-based gelator G3 can be self-assembled into an organogel (OG3) accompanied by strong AIE. OG3 shows reversible dual-channel response for S2-. The response process is based on the reversible deprotonation of the enol moiety in the tautomerized gelator G3'.
