The Effect of Electron Correlation on Excitonic Energy Transfer in a Synthetic Chromophore System

Recent experimental studies have shown how the quantum mechanism of electronic coherence is essential in the efficient energy transfer systems of the photosynthetic FMO complex found in green sulfur bacteria [1-3]. The FMO protein structure consists of a central magnesium atom surrounded by three identical monomers, each embedded with seven bacteriochlorophyll chromophore molecules, with an eighth additional bacteriochlorophyll chromophore between each of the three monomers [4]. The FMO acts as a mediator, efficiently facilitating the energy transfer from the light-harvesting antennae, known as chlorosomes, to the reaction center where the energy conversions of photosynthesis take place.
