J-AGGREGATES
The capture of light and efficient transport of energy is an increasingly important topic in chemical research. Photosynthetic light harvesting systems, comprised of aggregated, closely packed chromophores, exhibit excellent energy transport capabilities.

To study energy transport in these supramolecular organic systems, we are using a combined approach of microscopy and spectroscopy to quantify exciton migration along these one-dimensional molecular aggregates and monitor their spectral behavior under low temperature conditions.
J-aggregates are uniform, supramolecular structures spontaneously formed from individual dye molecule interactions solution. Interestingly, these synthetic aggregates can be studied as model one-dimensional light harvesting systems. J-aggregates exhibit remarkable optoelectronic properties as compared to the individual molecules of which they are constituted.
