Recognition of atomic-level difference in porphyrin dyads for self-sorted supramolecular polymer growth

Abstract

Porphyrin dyads (PD_Ms, where M = Zn and Cu) composed of diphenylporphyrin and tetraphenylporphyrin units, designated as ^DPD_Ms and ^TPD_Ms, respectively, exhibited remarkable differences in the molecular assemblies depending on the coordination metal ion. Furthermore, ^TPD_Ms showed self-sorting behavior during the formation of supramolecular assemblies through the recognition of atomic-level difference.
