Patent ID: 7678299

Claim:
A stock solution for production of nonlinear-optical materials using a wet coating method, comprising a nonlinear-optically active organic compound satisfying either condition (i) or (ii): (i) the nonlinear-optically active organic compound further comprising at least one cross-linkable functional group comprising a hydrolysable silyl group; and the nonlinear-optically active organic compound is a push-pull π-conjugated compound represented by Formula (1), or (ii) the stock solution further comprises a matrix-forming compound having at least one cross-linkable functional group comprising a hydrolysable silyl group; and the nonlinear-optically active organic compound is represented by Formula (2): wherein in Formula (1), Z 1 to Z 3 each are independently an aromatic group which may have substituents; L is a π-conjugated group which may have substituents; A is an electron-withdrawing group which may have substituents; and m is 0 or 1, wherein Z 1 to Z 3 , L and A each may be linked with any other group to form a ring structure; and at least one of Z 1 to Z 3 , L, and A has one or more cross-linkable functional groups: wherein in Formula (2), Z 4 to Z 6 each are independently an aromatic group which may have substituents; D is a π-conjugated group which may have substituents; E is an electron-withdrawing group which may have substituents; n is 0 or 1; and Z 4 to Z 6 , D, and E each may be linked with any other group to form a ring structure and may have one or more cross-linkable functional groups.
