    摘要： 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 &pgr;-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. The bridge also contains an unlocked conjugate diene unit to connect the the bridge ring and the acceptor. Another exemplary preferred chromophore includes an electron donor group, an acceptor, and a bridge structure therebetween, wherein the acceptor is a five- or six-membered ring locked tricyano electron acceptor. Another exemplary preferred chromophore includes an electron donor group, an electron acceptor group, and a bridge structure therebetween, with the bridge structure including a bithiophene unit. A preferred host polymer for the chromophores is poly[bisphenol A carbonate-co-4,4′-(3,3,5-trimethylcyclohexylidene)diphenol carbonate].

    摘要： Compositions for use in non-linear optical devices. The compositions have high first molecular electronic hyperpolarizability (.beta.) and therefore display high second order non-linear optical properties when incorporated into non-linear optical devices. The acceptor and donor groups which are used in the compositions, along with the .pi.(pi)-bridge length is chosen to optimize second-order non-linear optical responses.
