BiographyAnna Gudmundsdottir is a physical organic chemist with research interest in reactive intermediates, reaction mechanisms, organic photochemistry, solid state photoreactions and materials science. After earning a BS degree from the University of Iceland, she obtained a M.Sc. and PhD from the University of British Columbia. She did her PhD dissertation with Professor J. R. Scheffer, studying asymmetric induction in the solid state. In 1994-95, she was a visiting scientist with Professor P. J. Wagner at the Michigan State University and investigated photoinduced radical cleavage reactions. Between 1996 and 1998, she was a NATO postdoctoral fellow with Professor M. S. Platz at The Ohio State University, studying reactive intermediates. In 1998, she joined the faculty at the University of Cincinnati. She studies reactive intermediates in solution and in the solid state, polyanilines and photoreleasable protecting groups for controlling photorelease in various applications. She was awarded an NSF CAREER Award (2001-2006) for her research on triplet alkyl nitrenes in solution and the solid state. Better understanding of these intermediates in the solid state is expected to lead to better design of organic crystals for new materials. Possible applications include photolithography, photoaffinity labels for biological molecules, and organic magnets.

Photorelease of Alcohols
We are interested in slow release of alcohols since they are used as fragrances in applications such as body care and household cleaning goods. One of the drawbacks of using volatile alcohols in fragrances is that the desired aroma is perceived for a relatively short time in applications. Thus by forming an ester of a volatile alcohol with 2-benzoyl benzoic acid, it is possible to release the fragrance in a controlled manner over an extended time period by exposure to light. Photolysis of 2-(2-isopropyl-benzoyl)-benzoate ester derivatives in various solvents and in thin films results in the liberation of the alcohol moiety from the ester.
Conductive Polymers (or Synthetic Metals)
Polymers, which conduct electricity as efficiently as metals, if realized, would open the way to many new applications such as light-emitting diodes and flexible circutis. According to charge transfer models, the conductivity of conjugated polymers is limited by charge transfer between metallic islands and amorphous regions of the polymer. Our approach focuses on improving the bulk conductivity of polyaniline by introducing crosslinkers into the polymer in such a way as to prevent disruption of the packing arrangement in the crystalline regions. Furthermore, we will synthesize new derivatives of polyaniline with novel aniline monomers and use molecular recognition to obtain highly crystalline and conductive polymers.
