Synthesis and Properties of Aromatic Compounds

Abstract A combination of spectroscopy (UV/Vis absorption, emission, and circular dichroism), microscopy (AFM and TEM), and computational studies reveal the formation of non‐centrosymmetric homochiral columnar subphthalocyanine assemblies. These assemblies form through a cooperative supramolecular polymerization process driven by hydrogen‐bonding between amide groups, π–π stacking, and dipolar interactions between axial BF bonds.
