Ohio University’s Chemistry & Biochemistry Colloquium Series presents Dr. Alexis Ostrowski on “Harnessing photochemistry and photophysics of metal complexes for responsive materials”, Monday, Oct. 15, from 4:10 to 5 p.m. in Clippinger 194.
Dr. Alexis Ostrowski
Ostrowski is Assistant Professor of Chemistry at Bowling Green State University.
Abstract: We are designing new materials that take advantage of the unique photochemistry and photophysics of metal-coordination complexes to create responsive behavior. We use both natural polymers, as well as synthetic polymers with designed ligands that coordinate transition metal ions. By tuning the choice of ligand or metal ion, we can tune the reactivity due to the changing metal-ligand bind-ing interactions. We have integrated such metal-coordination bonding into polysaccharide-based materials to create photoresponsive hydrogels.[1,2] These gels showed changes in mechanical properties and pore size after light irradiation, and could be used as scaffold mate-rials for tissue engineering.[3] We are now designing new photoresponsive materials utilizing other natural metal coordination moieties.
The host is Dr. Jessica White, Assistant Professor of Chemistry & Biochemistry at Ohio University.
Colloquia are Mondays from 4:10 to 5 p.m. in Clippinger 194.
