ABSTRACT:
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.
