Abstract:
A method of making a multilayer structure having macroscopic second order nonlinear optical properties, the method comprising the steps of:contacting a substrate having ionic adsorption sites with a first charged polyion to form a first layer of the multilayer structure;ceasing contact of the substrate with the first charged polyion; and thereafter,contacting the substrate with a second charged polyion having a charge opposite to that of the first charged polyion to form a second layer of the multilayer substrate, wherein at least one of the polyions comprises nonlinear optical chromophoric side chains that are rod-like mesogens, and wherein the second contacting step causes the side chains to self-align into an ordered arrangement and exhibit macroscopic even-order nonlinear optical properties corresponding to a d33 value of greater than 0.1 pm/V, and wherein at least one of the polyions is formed from a polymer synthesized from an addition reaction of aniline and a compound having two epoxide rings.
