Going through the motions: The molecular cooperative motion between azobenzene moieties and photoinert cyanobiphenyl groups can be confined to nanoscale mesogenic domains by microphase separation of a triblock copolymer with a poly(methyl methacrylate) (PMMA) matrix (see picture). Films of the copolymer have a large anisotropy, stable birefringence, and improved transparency due to elimination of the scattering of visible light.
