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 58):
The nonlinear optical material according to  claim 47 , wherein the donor structure D is represented by the formula D-1-2: 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 saturated heterocyclic ring optionally having a substituent, or \n R D 4  and R D 5  form, together with the nitrogen atom to which they are attached, with the aryl carbon atom to which said nitrogen atom is attached, and with the aryl carbon atom which is adjacent to said carbon atom, a heterocyclic ring containing the nitrogen atom as a hetero atom and optionally having a substituent.
