TITLEUnderstanding Energy and Electron Transfer Through Time-Resolved Spectroscopy
ABSTRACT: The solar energy-conversion challenge involves many areas of science, and our contribution focuses on the fundamental understanding of the properties of electronic excited states that play a role in photoinduced energy transfer and photoinduced-multielectron-redox reactions. Within this context, we explore excited state dynamics and couplings of cyano-bridged metallo-dimers (Me-CN-Me’), oligomers, and nanoparticles. The talk will focus on coordination compounds studies of Ru based coordination compounds using 1-D and 2-D UV-Vis ultrafast time-resolved spectroscopy as a tool to understand the evolution of those excited states.
BIOProfessor Kleiman received her undergraduate Physical Chemistry degree from the Univ of Buenos Aires (Argentina), and her PhD from the University of Illinois @Chicago (US). After working in National Laboratories in Washington DC, Dr. Kleiman moved to Gainesville to start her independent professorial career in 2001, where she is currently a faculty in the Department of Chemistry at UF. Dr Kleiman has received several national and international awards and has been named Visiting Professor in universities in Spain and Argentina. Her research area of expertise is ultrafast laser spectroscopy of light-harvesting materials, exploring fundamental studies to understand how synthetic materials interact with light. Her work has been primarily funded by the Department of Energy and the National Science Foundation and it includes collaborations with scientists in the US, France, and her native Argentina. Her scientific and life experiences have led her to pursue new teaching horizons, developing an interdisciplinary course which combines her heritage as a Latina with her chemistry expertise (Chemistry in the Cocina Latina). She has received several teaching awards and has been recognized for her work as an international educator. She is the current academic co-director of two UF programs (i-REU and TASSEP) facilitating student opportunities to take classes and perform research abroad, in more than 10 different countries. In 2020, Prof Kleiman presented a TEDx talk about the subjectivities of scientific research and the implications of research outcomes based on the diversity of the research team.
