Light‐driven chirality: Sequential light‐driven isomerization of prochiral, bis(azobenzene)‐containing amino acids results in the formation of chiral entities that have been characterized by different techniques. Metal nanoparticles conjugated with these amino acids retain the photoswitching properties and show conformation‐dependent magnetic susceptibility that can be reversibly controlled by irradiation
光驱动手性:前手性含双(偶氮苯)的氨基酸的顺序光驱动异构化导致形成手性实体,该手性实体已通过不同技术表征。与这些氨基酸缀合的金属纳米颗粒保留了光开关特性,并显示出可以通过辐照可逆地控制的构象依赖性磁化率(见图)。
