Mesoscopic helical architectures via self-assembly of porphyrin-based discotic systems.

Abstract

Mesoscopic super-helices with preferred helicity have been serendipitously formed from the self-assembly of electroactive extended core discotic molecules. The investigation at dilute concentrations reveals intramolecular hydrogen-bonding and π-π stacking interactions as the driving force of the chiral self-assembly at different length scales.
