Hydrogen‐Bond‐Directed Orientation in Nonlinear Optical Thin Films

Abstract

A simple and effective method for the self‐assembling of thin films with directional ordering perpendicular to the substrate surface (see Figure) is reported. These films are grown on amorphous glass substrates and show second‐order nonlinear optical effects of the order of 5 pm V –1 . The ordering in these films can be maintained over large thicknesses (∼800 nm), and they are homogeneous over the area of the thin film.
