Abstract

Poled-polymers are promising materials for photorefradive applications. They have low dc dielectric constants, good electro-optic properties, high structural flexibility and can easily form a variety of thin-film and waveguide devices. Photorefractivity in polymers is of current interest because the newly observed photorefradive effect in polymers^1-3 needs to be better understood in order to further improve and optimize the capabilities of future integrated organic photorefractive devices. We report the observation of the photorefradive effect in an acrylate ester polymer containing the tricyanovinylcarbazole group with an alkylene spacer (Fig, 1). Polyvinylcarbazole is well known for its photoconductive properties and therefore no transport agent needs to be added.
