Light harvesting and charge transport functionalities of cylindrical molecular aggregates (CMA) composed of porphyrin and cyanine dye molecules are investigated using femtosecond laser spectroscopies. Experiments find that energy transfers between the inner and outer cylinder walls on the sub-picosecond time scale. Energy migration parallel to the long axis of the cylinder is under investigation.
