PURPOSE: To obtain a nonlinear optical material which lessens flocculation, crystallization and orientation relaxation at a high content and has high quadratic and cubic nonlinear optical characteristics by dissolving or dispersing specific compds. consisting of π electron conjugation-based cyclic compds. into a polymer.
CONSTITUTION: This nonlinear optical material contains the nonlinear optical material formed by dissolving or dispersing ≥1 kinds of the compds. expressed by formula 1 or their derivatives into a polymer material or this nonlinear optical material contains the conjugated/coordinated polymer of the formula I formed by conjugating or coordinating ≥1 kinds of the compds. expressed by the formula 1 or their derivatives with high polymer chains. In the formula, π1 to π3 denote the electron conjugation-based cyclic compds.; X, Y respectively denote a pair of combinations consisting of one selected from C, H, N or N to O; n denotes an integer of ≥0; D denotes an electron-donating group; R1 to R10 respectively denote hydrogen atoms or alkyl groups ; A1 to A3 respectively denote a hydrogen atom, alkyl group or the substituent (Z is a hydrogen atom, halogen atom, etc.) expressed by formula II.
