An N-annulated, rylene-based twistacene as scaffold for long supramolecular polymers

Abstract

The multistep synthesis of the N-annulated rylenecarbodiimide 1 is reported. The large p-surface and the operation of a fourfold array of H-bonding interactions between the trialkoxybenzamide units yield highly stable supramolecular polymers, the stability of which has been quantified by applying the denaturation model. The operation of these non-covalent interactions affords long 1D-supramolecular polymers that have been visualized by atomic force microscopy (AFM).
