A rational design strategy is proposed to develop excellent intelligent materials based on phosphorescent Ir(III) complexes displaying tunable luminescence response to electric field. Based on tunable electrochromic luminescence, an information “self‐encryption” method is developed by utilizing photoluminescence lifetime imaging microscopy without needing extra interference fluorescence. Furthermore, a multilevel information anticounterfeiting is realized utilizing the electric‐field‐induced changes in both luminescence colors and lifetimes.
