Abstract:

Several key advances have been made. In the field of photorefractive polymers, a new molecule was developed which resulted in photorefractive composites with unprecedented performance both in the visible and the near infrared regions of the electromagnetic spectrum. In the field of organic light emitting diodes several new barrelene molecules have been made, including some which are water soluble and can be used in schemes for self-assembling light emitting diodes. In addition, molecules with tunable ionization potentials that can be incorporated into photocrosslinkable polymers have been synthesized. In the field of two-photon absorption, molecules that initiate polymerization have been characterized in terms of their efficiencies relative to commercial photoinitiators and have been shown to have much higher efficiencies and new electron deficient molecules based upon dioxoborine heterocycles have been synthesized and characterized. Finally, new dopants with large dielectric anisotropies have been synthesized in order to lower the switching voltage for liquid crystal mixtures. Several undergraduate and graduate students received an interdisciplinary training in materials synthesis and characterization.
