摘要：

[GRAPHICS] Cationic porphyrins 1-3 bearing one, two, and four bicyclic guanidines form highly ordered chiral assemblies in aqueous solutions. The chirality is controlled by the type of the anionic counterpart and results from a spontaneous process. The chiral assemblies of 1-3 relate structurally to the complexes of achiral porphyrins with helical DNA. However, the presence of a chiral template (DNA, poly L-Glu were tested) is not necessary for formation of these specific chiral porphyrin assemblies.
