Abstract

Nonlinear-optic (NLO) compositions containing functionalized merocyanine dyes, such that the molecules, comprising the NLO-active compositions have a functional group at each end of the molecule and each functional group differing in reactivity, thus permitting stepwise reaction of each functional group, and NLO-active molecules prepared from hemioxonol dyes derviatived with (meth)acrylate or (meth)acrylamide groups, and their uses in devices such as second harmonic generators or polymer integrated optics.
