Abstract:
Problem to Be Solved: to provide a chromophore having a far superior nonlinear optical activity to conventional chromophores and to provide a nonlinear optical element comprising said chromophore. 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.

Claim (Index 56):
The nonlinear optical material according to  claim 47 , wherein the donor structure D is represented by the formula D-1: wherein\n at least one of R D 1 , R D 2 , and R D 3  independently 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; the rest independently represent a hydrogen atom or an alkyl group; and R D 1 , R D 2 , and R D 3  each may have the same or different substituents \n (when R D 2  and R D 3  are each attached to adjacent carbon atoms of the aryl of the donor structure D, \n (1) R D 2  and R D 3  may form, together with the two adjacent carbon atoms, a ring optionally having a substituent; and \n 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, or\n (2) R D 2  and R D 3  may form, together with the two adjacent carbon atoms, a heterocyclic ring containing an oxygen atom as a hetero atom and optionally having a substituent); and \n 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 \n 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 \n (a) R D 2  and \u2014NR D 4 R D 5  and (b) R D 3  and \u2014NR 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.
