Abstract

Solution: a chromophore comprising a donor structure D, a π-conjugated bridge structure B, and an acceptor structure A, the donor structure D comprising an aryl group substituted with a substituted oxy group; and a nonlinear optical element comprising said chromophore.

First claim

The invention claimed is:

1. A nonlinear optical material comprising a chromophore comprising a donor structure D, a π-conjugated bridge structure B, and an acceptor structure A, the donor structure D comprising an aryl group substituted with a substituted oxy group and the acceptor structure A being free of —SO 2 — and a host material in which the chromophore is dispersed, wherein the substituted oxy group is a hydroxyl group or a structure in which a hydrogen atom of a hydroxyl group is replaced with a substituent and the chromophore is represented by the formula IV-1-a:

wherein
n represents an integer of 1 to 5;
R D 1 represents an alkoxy group, an aryloxy group, an aralkyloxy group, a silyloxy group, an alkenyloxy group, an alkenylcarbonyloxy group, an alkynyloxy group, or a hydroxy group, and R D 1 may have a substituent;
R D 2 and R D 3 independently represent a hydrogen atom, an alkyl group, an alkoxy group, an aryloxy group, an aralkyloxy group, a silyloxy group, an alkenyloxy group, an alkenylcarbonyloxy group, an alkynyloxy group, or a hydroxy group, and R D 2 and R D 3 each may have the same or different substituents
(when R D 2 and R D 3 are each attached to adjacent carbon atoms of the aryl of the donor structure D,
R D 2 and R D 3 may form, together with the two adjacent carbon atoms, a ring optionally having a substituent);
R D 4 and R D 5 independently represent a hydrogen atom, an alkyl group, a haloalkyl group, a hydroxyalkyl group, an acyloxyalkyl group, a silyloxyalkyl group, an aminoalkyl group, or an aryl group, and R D 4 and R D 5 each may have the same or different substituents, or
R D 4 and R D 5 form, together with the nitrogen atom to which they are attached, a heterocyclic ring containing the nitrogen atom as a hetero atom and optionally having a substituent; or
(a) R D 2 and —NR D 4 R D 5 and (b) R D 3 and —NR D 4 R D 5 independently form, together with the carbon atoms to which they are attached, a heterocyclic ring containing the nitrogen atom as a hetero atom and optionally having a substituent; and
R A 1 and R A 2 independently represent a hydrogen atom, an alkyl group, a haloalkyl group, or an aryl group, and R A 1 and R A 2 each may have the same or different substituents.

2. The nonlinear optical material according to claim 1 , wherein the chromophore is represented by the formula selected from the group consisting of:

3. A nonlinear optical material comprising a chromophore represented by the formula selected from the group consisting of:

and a host material in which the chromophore is dispersed.
