Herein, a light and magnetism dual stimuli-responsive composite (SR-Fe3O4@AMEO@SP) was designed and synthesized, by assembling the light sensitive spiropyran (SP) with magnetism responsive SR-Fe3O4 particle. The resultant composite was characterized in detail and light/magnetism-triggered, structural and functional responses of it were evaluated systematically. Such solid-composite exerted sensitive to light stimulus properly attributing to the rough and uneven nature of SR-Fe3O4 surface, which provided a large interspace for SP conformational transformation. Based on these, SR-Fe3O4@AMEO@SP composites with dynamically and reversibly light/magnetism dual stimuli-responsive properties for potential application in catalysis and adsorption fields can be offered.
