UV light-triggered -to- isomerization of azobenzene usually results in the collapse of a self-assembly system owing to the breaking of molecular planarity. Interestingly, two totally opposite self-assembly trends have been detected when a -symmetric chiral gelator was irradiated by a circularly polarized light (CPL) with specific handedness, indicating that CPL could become a powerful tool in modulating the assembly behaviour of the photo-responsive system.
紫外线引发的偶氮苯异构化通常会导致自组装体系的瓦解，这是由于分子平面性的破坏。有趣的是，当用具有特定旋向性的圆偏振光（CPL）照射一种对称手性凝胶因子时，检测到了两种完全相反的自组装趋势，这表明圆偏振光可能成为调节光响应体系组装行为的有力工具。
