| 英文摘要 | Aromatic oligoamides of 2,6-diaminofluorobenzene and 1,8-diazafluoroanthrancene-2,7-diacid have been synthesized by a convergent method. The heptameric oligoamide can not only fold into a single helix but also hybridize into a highly stable double helix through intensive intermolecular aromatic stackings, which has been extensively characterized in the solid state by single crystal X-ray diffractions and in solution by H-1 NMR, NOESY, and UV/vis spectra. The K-dim values of the heptamer are over 10(7) L mol(-1) in various solutions at rt. The extensive interstrand interactions, enlarged diameter (5.4 angstrom), and lower torsion angles (13 degrees) render heptamer 1 readily to hybridize into a highly stable double helix based on spring-like extension mechanism.
