β¦ Synopsis
Two forms of a novel accordion-shaped non-linear optical polymer (NLOP) based on cis-and trans-1,2diaminocyclohexane and o-xylyl linkages were characterized by solution-and solid-state NMR spectroscopy. Model compounds and the monomers for both the cis and trans forms of these polymers were also investigated. The cis form is less rigid than the trans form, as demonstrated by the fluxional behavior of the cis model in the solution state.

The Langmuir-Blodgett (LB) film-forming properties of a number of novel azobenzene dye polymers are reported. The linear and second-order non-linear optical properties of the films have been studied using ellipsometry, visible spectroscopy and Pockels effect measurements. As monolayers, the effectiv
We have used combinations of light, heat, and electrostatic fields to investigate the orientation of nonlinear azo-chromophores chemically incorporated into high glass transition temperature ( T g ) polyimides. A number of nonlinear optical polyimides have been synthesized in which the interaction b
