Big Energy Seminar Presents: Design Principles for Light Harvesting
Start Date: 3/1/2013Start Time: 4:00 PM
End Date: 3/1/2013End Time: 6:00 PM
Event Description:
Photosynthetic light harvesting complexes are sophisticated multichromophoric assemblies used to regulate and concentrate photo-excitations for delivery to reaction centers under wide-ranging incident irradiances. They provide wonderful model systems for the study of energy transfer mechanisms in well-defined structures. From those studies, several broad lessons have been learned that were described in a recent article. As concluded in that article, the next step appears to be elucidating how can we write a blueprint to ‘make something’ based on what we have learned from photosynthetic complexes. Despite the thousands of studies reported on energy transfer, researchers have not really established clear design principles except for the use of an energy gradient. However, most photosynthetic light harvesting complexes do not incorporate a substantial internal energy gradient directing energy flow, that is, only one of two chemical types of chromophores are used. I will discuss an example of a light harvesting ‘circuit’ and describe various examples of energy transfer in light harvesting. Finally, I will mention new experiments that enable us to perform multidimensional nonlinear spectroscopy without using femtosecond lasers.
