Figure 1

(a) The molecular arrangements of diphenylalanine hosting water molecules in nanotubes and nanowires in the hexagonal lattice system after Rietveld refinement [59]. (b) Schematic diagram of self-assembled FF in nanofibers, microtubes, and microrods [65]. (c) Schematic diagram of coassembled FF and Boc-FF peptide nanotubes. The red molecule represents an FF building block, and the blue molecule represents a Boc-FF building block [74]. (d) Schematic diagram of a cationic dipeptide and polyoxometalates (POMs) coassembling to hybrid supramolecular structures [77].
