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. Another exemplary preferred polymer is a crosslinked polymer made from crosslinkable star-shaped hi…
