Since the first discovery of liquid crystals (LCs), the stimuli‐responsive nature of the mesophases has made them promising optical materials. Photoluminescence (PL) via excited‐state intramolecular proton‐transfer (ESIPT) is a unique photophysical process giving anti‐Kasha‐type dual emission from excited‐state tautomers. The PL is associated with aggregation‐induced emission (AIE) and/or AIE enhancement, allowing to realize a quick response of amplified spontaneous emission (ASE) from the LC media heavily doped by ESIPT molecules.
