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.

Abstract Plastics are one of the greatest inventions 20 th century that bring convenience to mankind. Owing commercialization plastics, plastic pollution has become a petrifying environmental issue as demand for products overwhelms recycling rates. However, conventional methods (i.e., pyrolysis and gasification) require high pressure temperature treat waste plastic, resulting in ineluctably energy‐waste secondary pollution. On contrary, selective catalylic technologies provide green approach degrade plastics whilst also reforming them into value‐added chemicals fuels. In this review, innovative approaches, including photocatalysis, electrocatalysis, photoelectrocatalysis, have been comprehensively reviewed from perspective sustainable use resources. Distinctive emphasis is placed on highlighting merits each technology enlightening state‐of‐the‐art modification strategies strengthen pillars catalytic activities. The transformation with above techniques elaborated terms reaction conditions various substrates. With feasibility breakdown displayed study, insights challenges prospects upcycling underscored well facilitate society moving toward circular economy.
