    摘要： This invention is comprised of new nonlinear optic polymers and a new Lanir-Blodgett (LB) film deposition scheme for which these polymers were designed. The invention is unique because it produces an electro-optic film which has never undergone electric-field poling nor high temperature treatment. It eliminates the dilution effect of the long hydrophobic alkyl groups, and creates stronger ionic bonds between the polymer chains. Finally, the invention reduces the time to make a film of a given thickness by at least half by virtue of depositing two polymer layers per stroke. The new polymers are comprised of asymmetric chromophores linked head-to-head by alternating two different kinds of bridging groups. One of the bridging groups contains one or more ionic groups, and the other bridging group contains one or more non-ionic, hydrophilic groups.

    摘要： The present invention discloses new polymers which can assume an accordion-like conformation of the backbone. These polymers are prepared by the copolymerization of two difuntional, chemically precoupled precursors to chromophoric units. The resulting polymers have a head-to-head, tail-to-tail topology (a syndioregic arrangement of rigid units along the polymer backbone), and the molecular units are designed to fold into an "accordion" conformation. This useful microstructure (a three-dimensional conformation) forms spontaneously (self-assembles); or, it can be brought about by field-assisted processing. Films and fibers of these polymers have useful second-order nonlinear optical properties, and may be used for the modulation and switching of optical communications signals.
