This is the final report of a one-year, Laboratory-Directed Research and Development (LDRD) project at the Los Alamos National Laboratory (LANL). Organic materials have shown great promise for near term applications in electro-optic, photorefractive, and electroluminescent devices. Electro-optic materials are useful for fast optical switching, photorefractive materials are essential for optical computing and information storage; electroluminescence is the basis for light-emitting diodes (LEDs). Existing organic electro- optic and photorefractive materials require a breakthrough in techniques to control the microscopic molecular orientation while maintaining economical processing. Our unique approach addresses this problem by building ordered superlattices by molecular engineering. Existing organic LEDs suffer from device breakdown, probably catalyzed by interfacial defects. Our approach allows molecular level control of the electronic properties of the polymer interfaces by designing charge transport layers to isolate the active polymer layer. This project sought to create electro-optic and photorefractive materials by engineering rationally designed nonlinear molecular building blocks into multilayer thin films using self assembly techniques.
