    • A kind referee indicated the similar behavior between cyanine dyes, which form J aggregates in water and are disassembled by methanol, and our porphyrin assemblies which, however, are formed only in nonpolar solvents. Furthermore, similar effects such as red-shifted and broadened absorption bands, as well as the precipitation of fluffs, which are disrupted upon shaking, were observed with a water insoluble porphyrin, which was slightly soluble in methanol. These latter aggregates could be seen with TEM and had dimensions between 50 and 110 nm. It appears that this same mesoscopic behavior can thus be engineered with different supramolecular interactions. In our case, because the same functional groups are present as those in the natural self-assembling BChls, we are surely mimicking these antenna systems only in the absence of solvents which can compete for hydrogen bonding or zinc ligation.
