摘要: A series of low-molecular-mass organogelators (LMOGs), dimeric dendrons based on natural amino acids, glycine. and aspartic acid, with different aliphatic spacers have been synthesized their self-assembly behavior structure−property relationship studied. Transmission electron microscopy (TEM), atomic force (AFM), infrared spectroscopy (IR), small-angle X-ray scattering (SAXS) were employed to characterize the self-assembled structures examine effect length gelation. It was found that all gels thermoreversible stable for more than half a year at room temperature. The longer displayed enhanced gelation ability. SAXS patterns xerogels G2SnG2 (n = 6, 8, 10) showed periodical reflections could be attributed formation hexagonal columnar phase, whereas G2S15G2 formed lamellar structure. Hydrogen bonding π−π stacking interactions evidence...
