Patent ID: 7258822

Claim:
An organic nonlinear optical material comprising 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 the nonlinear optical activity; wherein Z 1 to Z 3 are 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 Z 3 -L m has, from one terminal thereof to the other terminal, five or more unsaturated bonds which form one conjugated system; and at least two of Z 1 to Z 3 , L and A may be connected so as to form at least one ring structure.
