Abstract

There is provided an organic nonlinear optical material including a polymer binder and a compound represented by the following Formula (I):

wherein, in Formula (I),
R 1 and R 2 each independently represent a substituted or unsubstituted alkyl group or a substituted or unsubstituted aryl group;
R 3 represents a hydrogen atom, a substituted or unsubstituted alkyl group, or a substituted or unsubstituted aryl group; and
L represents a divalent linking group connecting a nitrogen atom and an oxopyrroline ring having a dicyanomethylidene group in a π-conjugated system containing an azo group (—N═N—).

First claim

What is claimed is:

1. A compound represented by the following Formula (II):

wherein, in Formula (II),
R 1 and R 2 each independently represent a substituted or unsubstituted alkyl group or a substituted or unsubstituted aryl group;
R 3 represents a hydrogen atom, a substituted or unsubstituted alkyl group, or a substituted or unsubstituted aryl group;
A 1 and A 2 each independently represent a substituted or unsubstituted aromatic group;
X represents —CR 4 ═CR 5 —, —C≡C—, —CR 6 ═N—, —N═CR 7 — or —N═N—;
Y represents —CR 8 ═CR 9 — or a substituted or unsubstituted aromatic group;
R 4 , R 5 , R 6 , R 7 , R 8 and R 9 each independently represent a hydrogen atom, a substituted or unsubstituted alkyl group, or a substituted or unsubstituted aryl group;
l and n each independently represent an integer of 0 to 3;
m, o, and p each independently represent an integer of 1 to 3;
each of R 4 's, R 5 's, R 6 's, R 7 's, R 8 's, R 9 's, A 1 's, A 2 's, X's, Y's, l's and m's may be the same or different, and at least one of X's contains —N═N—.
