Two novel quadruple hydrogen-bonding motifs: the formation of supramolecular polymers, vesicles, and organogels
摘要:
Two new hydrazide-based quadruple hydrogen-bonding motifs are described. Dipodals based on these two motifs are revealed to form supramolecular polymers, which can further aggregate to form vesicles and/or organogels in hydrocarbons. The quadruple hydrogen-bonding motifs are characterized by the Xray diffraction and (2D) H-1 NMR experiments, while the vesicles and organogels are evidenced by SEM, AFM TEM, and fluorescent microscopy.
