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.

Second-order nonlinear optical chromophores containing dioxine and/or bithiophene as conjugate bridge and devices incorporating the same

Sterically stabilized second-order nonlinear optical chromophores and devices incorporating the same are embodied in a variety of chromophore materials. An exemplary preferred chromophore includes an electron donor group, an electron acceptor group and a bridge structure therebetween, with the electron acceptor group being double bonded to the bridge structure. In a preferred embodiment, the bridge structure also includes at least one bulky side group. Another exemplary preferred chromophore includes an electron donor group, an electron acceptor group and a ring-locked bridge structure between the electron donor group and the electron acceptor group. The bridge structure comprises, for example, two protected alicyclic rings or ring-locked trienone. Another exemplary preferred chromophore includes an electron donor group, a ring-locked tricyano electron acceptor group, and a bridge structure therebetween. In a preferred embodiment, the electron acceptor group comprises an isophorone structure.
