在用线性偏振光照射两亲性二芳基乙烯衍生物（其在水中显示球体和纤维状态之间的光致形态转变）时，在TEM图像中观察到纤维在偏振方向上的伸长。的扩散运动被抑制在垂直于所产生的纤维的方向，通过添加聚苯乙烯（PS）珠的轨迹跟踪所揭示的。当使用非偏振紫外光时，TEM图像显示没有各向异性特征，PS珠的扩散是各向同性的。 这些结果提供了一种手段，各向异性的超分子结构的形态光控。
Upon irradiation of an amphiphilic diarylethene derivative (which shows a photoinduced morphological transformation in water between sphere and fiber states) with linearly polarized light, elongation of the fiber in the direction of polarization was observed in TEM images. The diffusive motion was suppressed in the direction perpendicular to that of the generated fiber, as revealed by means of trajectory tracking of added polystyrene (PS) beads. When unpolarized UV light was used, the TEM image showed no anisotropic features and the diffusion of PS beads was isotropic. These results provide a means for anisotropic photocontrol of the morphology of supramolecular architectures.
