The synthesis of new electro-optic polymers.
This work involves the synthesis of two types of electro-optic monomers and their corresponding polymers. The first type of monomers contain the p-oxy-α-cyanocinnamate structure and were synthesized from ω-hydroxyalkoxy-substituted benzaldehydes and methyl cyanoacetate. These ω-hydroxy-α-cyanoester …

Electro-Optic Properties of Self-Assembled Non-Linear Optical Polymers
Electrostatic self-assembly was used to fabricate several samples of polymers known to have non-linear optical behavior. These samples characteristics were measured with interferometry and their electro-optic coefficients determined to be on the order that of LiNbO3. The self-assembled samples are …
