Fig. 10From: Photoinduced supramolecular chirality and spontaneous surface patterning in high-performance azo materialsPolarimetry results for azimuthal rotation in dependence on duration of illumination for a) 1, b) 2, and c) 3. The longer the duration of illumination or exposure time, the higher is the azimuthal rotation. The samples were irradiated by EPL with an ellipticity of ε=15∘Back to article page
