I want to investigate how we can take macromolecular
architectures and increase their potential for
utilitarian applications. I plan on engaging Hiram College undergraduates in this
unique field of chemistry to explore the possibilities of these topics
using transition metal organometallic complexes and dendritic
macromolecules.
The
ability to harness sunlight and transform it into chemical energy is a
process known as photosynthesis. A variety of compounds having the
ability to capture light and subsequently transfer the resulting energy
have been synthesized and their properties investigated. In my research
laboratory, we plan on exploring the role of novel metal-containing,
water soluble arborol-appended organic compounds that form aqueous gels
at ambient temperature for use as light harvesting centers. Such
materials have potential useful applications in the area of alternative
energy.
Currently, Brian Yeager (‘10) and Micheal Lipkin ('10), Madhu
Balasubramanian ('11) and Cynthia Martin ('11) are working on various
projects ranging from building macromolecular structures and optimizing
microwave reaction yields of building blocks to determining methods of
ion concentrations for long term water quality testing and studies
related to the White Wing Wood Ducks housed at the James H. Barrow Field
Station.
The students are exposed to new synthetic techniques in the
laboratory as well as instrumental methods of characterization
available at Hiram College. They also learn skills such as
technical writing, problem solving, teamwork and research ethics.
