A novel photoresponding ionic complex(PANDAZO) was prepared by the ionic self-assembly(ISA) of sodium polyacrylate(PANa) and azobenzene chromophores(NDAZO). The ionic complex forms an interdigitated lamellar structure with full overlap of the side chains. The optical anisotropy was investigated by using a polarization pulse laser(355 nm). Furthermore, a high photoinduced birefringence(Dn = 0.365) was measured by using a continuous 488 nm laser as the pump light.
