US Classification:

359321, 252582, 359345

Abstract:

Sterically stabilized polyene-bridged second-order nonlinear chromophores and devices incorporating the same are embodied in a variety of chromophore materials, and particularly in chromophore materials are configured within an oxygen-free operating environment. An exemplary preferred chromophore includes an electron donor group, an electron acceptor group and a -conjugate bridge structure therebetween. The bridge is a polyene structure having a five-, six- or seven-membered ring to lock one carbon-carbon double bond. The bridge contains an unlocked conjugate diene unit which connects the bridge ring and the acceptor. 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 includes a fused double-or triple-ring structure which functions to lock two or three double bonds.

Abstract:

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 ring-locked bridge structure therebetween, with the bridge structure being directly connected to the electron donor via a single bond. 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, with two free double bonds, one located between the donor and the bridge and the other located between the (fused) ring bridge and the acceptor.

Abstract:

Polymers containing polyene-bridged second-order nonlinear optical chromophores and devices incorporating the same are disclosed. The chromophores are functionalized and incorporated into a series of polymers ranging from linear polyesters, linear poly[ester-imide]s, chain-crosslinked polyesters/poly[ester-imide]s, to crosslinked star-shaped/dendritic macromolecules. An exemplary preferred polymer is a linear chain polymer formed from a dihydroxy-functionalized polyene-bridged chromophore, a diacid or diacid dichloride, and a diol. In a preferred embodiment, the diol structure also includes at least one imide group. Another exemplary preferred polymer is a crosslinked polymer comprised of a linear chain polymer formed from a dihydroxy-functionalized polyene-bridged chromophore, a diacid or diacid dichloride and a diol. The crosslinking is realized by thermally induced cyclolization of trifluorovinylethers which are attached to the diol co-monomer and/or chromophore in the linear chain polymer chain. In a preferred embodiment, the diol structure also includes at least one imide group.
