Abstract
Light can induce rich and diverse topographical transformations of initially flat films composed of photoresponsive, azobenzene-functionalized liquid-crystalline polymer networks. The N-fold symmetry of the topography of the photoinduced response of defect-containing azo-LCN films is examined by T. J. White and co-workers on page 5880. It is found to be inherently coupled to the strength of the defect, confirming that the director profile emanating from the topological defect governs the behavior. The topography of a film subsumed with a +10 defect resting on water after exposure to light is shown here.
