Self-aggregation processes are rarely reproducible owing to their dependence on various experimental parameters (aging of stock solutions, their concentration, concentration of working solutions, ionic strength, etc.). However, by enucleating the dependence from one parameter (in this case, the dependence of aggregation from the concentration of the working solutions), it has been possible to hierarchically control self-aggregation of the protonated form of tetrakis-(4-sulfonatophenyl)-porphyrin.
