Abstract Multiple stimuli‐responsive materials hold excellent potential for the next generation smart owing to their unique response external stimuli, providing a powerful impetus development of intelligent optical devices. The behavior common multiple are independent each other, causing lack multiplicity and identification information technology, which is easy decode. Herein, QIPA‐Eu‐1 QIPA‐Eu‐2 isomers were prepared from QIPA EuCl 3 ·6H 2 O in different solvent thermal conditions building sequential stimuli‐response (SSR) system. Solvent‐driven structural transformations into QIPA‐Eu‐3 occurred, along with color change fluorescence emission variation ascribed aggregates. Furthermore, displayed photochromic behaviors. Combining theoretical calculation well‐defined experiments reveal mechanism, it was found that light drove dihedral angles between quinoline nucleus adjacent benzene rings Finally, on basis stimuli‐induced stepwise responsive QIPA‐Eu‐1, logic gate time‐dependent dynamic anti‐counterfeiting pattern successfully constructed. This study provided new perspective design construction SSR system, showed promising fields data transmission encryption.
