Abstract
Second-order nonlinear optical (NLO) polyene-based chromophores sterically stabilized with a dioxine ring and NLO chromophores containing bithiophene derivatives, and devices incorporating the same, are disclosed. An exemplary preferred chromophore includes an aminophenyl electron donor group and a dioxine-containing bridge structure. Another exemplary preferred chromophore includes a ring-locked bridge structure with a dioxine unit and a bithiophene unit. Another exemplary preferred chromophore includes a bridge structure with a bithiophene unit and an isophorone-derived cyclohexene unit.
