在椭圆偏振激光照射下，在无定形和非手性偶氮苯聚合物薄膜中光学诱导了超分子手性。这种手性是偶氮苯发色团通过圆偏振和线偏振相结合的螺旋取向所致。螺旋利手可以通过入射的光利手来控制。
Supramolecular chirality was optically induced in amorphous and achiral azobenzene polymer films by irradiation of a laser beam with elliptical polarization. The chirality resulted from helical orientation of azobenzene chromophores by a combined process of circular and linear polarization. The helix-handedness could be controlled by incident light-handedness.
