A Pyridyl‐Monoannulated Naphthalene Diimide Motif Self‐Assembles into Tuneable Nanostructures by Means of Solvophobic Control

Abstract

The supramolecular self-assembly of the core-substituted naphthalene diimide bearing pyridyl motifs leads to the formation of a variety of nanostructures with pH and solvent control. The detection of HCl can be monitored by UV/Vis and fluorescence spectroscopy, as well as the naked eye, with a change in colour (blue to red, see figure). The cycle is fully reversed by the addition of triethylamine (TEA).
