Fluorescent self‐assembled liquid gels have been prepared for the first time through the use of a gelator showing aggregation‐induced enhanced emission. The photoluminescence, arising from the fibrous aggregates of the gelator, can be repeatedly switched by an electric field. Modulating the excitation light through electric‐field‐induced liquid‐crystal orientation offers new ways to achieve and explore electrically controllable photoluminescence.
