摘要：

Piggy-back porphyrins: The presence of a Lewis base remarkably affects the cooperative self-assembly of zinc porphyrins. Driven by the susceptibility of the monomer towards the axial ligand, monomer scavenging caused depolymerization of porphyrin aggregates, and dilution caused aggregation by a re-entrant phase transition. Model predictions were validated by dilution experiments. Chemical Equation Presentation © 2010 Wiley-VCH Verlag GmbH & Co. KGaA, Weinheim.
