Excited‐state intramolecular proton transfer (ESIPT) process brings about ultrafast keto‐enol tautomerism, which simultaneously induces the unique four‐leveled energy state cycle and concomitant multi‐emissions. Such transformation is easily affected by the environmental conditions, leading to intri...
