Zinc porphyrin functionalized with double long-chain alkylated L-glutamide (GTPP-Zn) wassynthesized for the first time, and its self-assembling behaviour was investigated in nonpolarorganic solvents. The uniqueness of this functionalized porphyrin is characterized by its drasticcolour change from dark green to purple via the formation of chirally stacked structures throughselective axial coordination on zinc with pyridine derivatives. In this paper, we report theversatility of the GTPP-Zn assembly process as a stimuli-responsive chiroptical switching systemand describe the remarkable ligand-specific induction of secondary chirality accompanied byaggregation morphological change.
