Fig. 1From: Photoinduced supramolecular chirality and spontaneous surface patterning in high-performance azo materialsChemical equation of photo-isomerization of an azo molecule. The light induced isomerization of an azo molecule depends on the orientation between transition dipole moment M and polarization state P of incident light. The probability of isomerization decreases from 0∘ (P ∥ M) to 90∘ (P ⊥ M)Back to article page
