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, three students [Martin J. Ross (‘09),  Maria Sember (‘10) and Brian Yeager (‘10)] are working on the synthesis and characterization of the arborol-terpyridine ligand for the project.  The students are exposed   to new synthetic techniques in the laboratory as well as instrumental methods  of characterization available at Hiram College.
