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.

具有光和磁双重刺激响应特性的SR-Fe 3 O 4 @ AMEO @ SP复合材料的合理设计

在此,通过将光敏螺吡喃(SP)与磁响应SR-Fe 3 O 4颗粒组装在一起,设计并合成了光磁双刺激响应复合物(SR-Fe 3 O 4 @ AMEO @ SP)。对所得复合材料进行了详细表征,并对其光/磁性触发的结构和功能响应进行了系统评估。这种固体复合物对光刺激敏感,适当地归因于SR-Fe 3 O 4表面的粗糙和不平整性质,这为SP构象转化提供了很大的空间。基于这些,SR-Fe 3 O 4可以提供具有动态和可逆的光/磁性双重刺激响应特性的@ AMEO @ SP复合材料,可潜在地应用于催化和吸附领域。
