Abstract:
A columnar supramolecular HDTP/HCTP polymer is prepared by simple addition of two oppositely charged triphenylene‐based monomers. 1H NMR indicates an ordered aggregate formation with parallel stacking of the aromatic subunits in aqueous solution. UV‐Vis and fluorescence spectra imply that HDTP and HCTP self‐assemble to construct H‐aggregates, in which two monomers have a strict geometric association with each other. A fiber‐like structure (and fiber aggregates) is also found in the solid state. The microstructure of the supramolecular polymer is also studied by WAXS. Based on the analyses, a tentative model for the columnar supramolecular polymer is proposed, which suggests the importance of directional π‐π interactions and strong multiple ionic bonds.
