Chiral transcription and retentive helical memory: probing peptide auxiliaries appended with naphthalenediimides for their one-dimensional molecular organization.

Right or left paradox: Homochiral, heterochiral and achiral peptide auxiliaries appended with naphthalenediimide (NDI, see figure) were employed to demonstrate chiral transcription. We report an interesting phenomenon coined as retentive helical memory. Remarkably, NDI-peptide conjugates were tuned into hierarchical 1D molecular assemblies of opposite helicity in case of homochiral peptide auxiliaries.
