Abstract

Light, (CCD) camera, action! Time-resolved synchrotron X-ray scattering measurements revealed that linear polarized light (LPL) caused reorientation of phase-separated mesoscopic amorphous cylinders within a light-responsive liquid crystalline (LC) matrix domain of a diblock copolymer (see scheme). Cooperative and synchronized motions occur at two hierarchical structures of the LC layer (molecular level) and the polymer domains (mesoscopic level).
