Abstract: The aggregation process of the tetraanionic H2TPPS and the tetracationic CuT4 porphyrins leads, in aqueous solution and in the presence of a suitable chiral template, to the formation of remarkably stable and kinetically inert chiral porphyrin heteroassemblies. These properties enable the aggregates to survive template chirality disruption and its complete removal from the solution, maintaining unaltered the imprinted chiral structure. The free-template "imprinted" porphyrin aggregate is an excellent mold for the amplification of its own structure
