High Carrier Mobility Photorefractive Polymers for Long Wavelength Operation
Abstract
High carrier mobility organic materials for future application in high-speed photorefractive materials have been synthesized and characterized. These materials are discotic columnar liquid crystals and crystals composed of self-assembling functionalized dendron molecules. Examples consisting of monomeric and polymeric materials functionalized with carbazole and trinitrofluorinone charge-transport moieties have been investigated. Stable homeotropically aligned columnar liquid crystal samples have been produced. A characterization facility including three photoconductivity and two photorefraction measurements has been assembled. Initial measurements on carbazole-containing materials confirm a high hole mobility of the magnitude lO to the -3 lO - to the -2 cm2/Vsec. These mobility values confirm that this approach to high mobility materials hold considerable promise. Our results indicate that a new family of self-assembling, electronically and optically functional materials can be tailored from this class of materials.
