Nonlinear optical material

Abstract

Abstract PURPOSE:To obtain a high nonlinear optical effect by using a specific compd. so that inverse symmetry is hardly obtainable in a bulk state such as crystal or thin film and the material has substantially no absorption in a visible region. CONSTITUTION:The compd. expressed by formula I is used as this material. In formula I, D denotes an electron-donating group; C denotes a monovalent org. group; R denotes a hydrogen atom, alkyl group, aryl group or heterocyclic group; (m) denotes 1-3 integer; (n) denotes 0-3 integer. This compd. is usable as the nonlinear optical material in various forms such as single crystal, powder, soln. the thin film (Langmuir-Blodgett film, vapor deposited film, etc.) deposited on a base or the form of blending the same into a polymer or liquid crystal molecules. The material which has substantially no absorption in the visible region is obtd. and the inverse symmetry is hardly obtainable in the form of use. In addition, high second harmonic waves are generatable.
