摘要: Four Phe–Ala lipodipeptides with different stereochemical structures are observed to self-assemble into twisted nanoribbons in water. The handedness of the is controlled by chirality phenylalanine near alkyl chain, while stacking phenyl and carbonyl groups determined alanine at C-terminal. homochiral heterochiral parallel antiparallel β-sheet structures, respectively. 1H NMR, FTIR, X-ray diffraction, circular dichroism characterizations indicate that these phenomena mainly driven interaction between neighboring H-bonding among amide groups.
