Self-assembling achiral and chiral porphyrin trimers based on benzene tricarboxamide exhibit amplification of chirality only in solvents in which the assemblies are dynamic enough to rearrange their constituting components. Self-assembling achiral and chiral porphyrin trimers exhibit amplification of chirality only in solvents where dynamic exchange of their components occurs.
