Abstract
An epoxy based polymer with nonlinear optical azo chromophores was des igned to contain anionic groups to induce water solubility and self as sembly. Using this polyanion with a polycation, multilayers were prepa red on a glass substrate by alternating adsorption from dilute aqueous solutions. The azo chromophores in the confined layer of the polyanio n in the multilayer films self-assemble into a noncentrosymmetric alig nment and demonstrate second order optical nonlinearity (d(33) = 19 pm /V).
