ABSTRACT:
The present invention provides an organic nonlinear optical material including an organic compound having nonlinear optical activity dispersed in or bonded to a polymer binder, wherein the material contains a tertiary amine derivative represented by the following formula (1) as the organic compound having nonlinear optical activity, and an organic nonlinear optical element using the same.In the formula, Z1to Z3are independently aromatic groups optionally having a substituent; L is a π conjugated group optionally having a substituent; A is a π conjugated electron-attractive group which includes a ring structure optionally having a substituent; m denotes 0 or 1; a π conjugated system denoted by Z3-Lmhas, from one terminal thereof to the other terminal, five or more unsaturated bonds which form one conjugated system; and at least two of Z1to Z3, L and A may be connected so as to form at least one ring structure.
