Functional novelties employed in light harvesting by diverse photosynthetic systems

 

Abstract:

 

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 [1]. They provide wonderful model systems for the study of energy transfer mechanisms in well-defined structures [2]. I will describe a few examples of ultrafast energy transfer in photosynthetic light harvesting, including the incredible use of nominally dark higher excited states of carotenoids to distribute excitation energy in LH2 from purple bacteria [3]. I will address the current status and issues regarding coherent ultrafast energy transfer in light harvesting complexes of cryptophyte algae.
