    摘要: The present invention introduces a novel route toward microstructural orientation into organic films, using multiple hydrogen-bonding to self-assemble chromophore molecules into electro-optic films in a net polar orientation. High­quality, thick films (up to micrometers) with molecular net dipole orientations can be fabricated under vacuum in hours. The film microstructure is intrinsically acentric; and the orientation is robust.

    摘要: Sterically stabilized polyene-bridged second-order nonlinear 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 pi-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. A preferred host polymer for the chromophores is poly[bisphenol A carbonate-co-4,4'-(3,3,5-trimethylcyclohexylidene)diphenol carbonate].

    摘要: Optically non-linear materials suitable upon repeated Langmuir-Blodgett dipping for forming Z-type (head-to-tail) films for second harmonic generation include hemicyanine dyes which are very unsymmetrical, i.e. which have hydrophobic substituents differing in size by at least 4 carbon atoms, each end of a hydrophilic chromophore. A suitable dye is E-N-octadecyl-4-[2-(4-dibutylaminophenyl)ethenyl]quinolinium iodide.
