H-bond and π–π stacking directed self-assembly of two-component supramolecular nanotubes: tuning length, diameter and wall thickness

A series of supramolecular nanotubes with fine-tuned length, diameter and wall thickness were obtained from co-assembly of an L-glutamic acid based bolaamphiphile (HDGA) and melamine with different molar ratios. The changes in tubular nanostructures were found to be dependent on different self-assembly mechanisms.
