Two conjugated molecules based on triphenylamine and 1,3‐indandione have been synthesized by employing Knoevenagel condensation. Both materials demonstrated aggregation‐induced emission behavior, and solvato‐ and piezochromic properties. These red luminescence materials are able to respond to F − and I − sensitively. The emission wavelength changed by almost 100 nm in the presence of F − and I − , and could be observed by the naked eye under daylight and UV light.
