苝酰亚胺——手性表面活性剂复合物在溶液中自组装行为的研究(英文)

研究制备了苝酰亚胺——手性表面活性剂复合物N,N′-双(2-(季铵基乙撑))-3,4,9,10-苝二酰亚胺-双((3R)-3,7-二甲基辛基-6-乙烯基)磷酸盐,详细研究了其在乙醇/正己烷,乙醇/正辛烷溶液中的自组装行为及组装机理。结果表明,该复合物在乙醇/正己烷溶液中组装为纳米管,在乙醇/正辛烷溶液中组装为纳米带。对其组装机理研究表明,该分子在溶液中组装为不同形态的纳米结构是π-π相互作用,疏水作用及手性诱导等多种作用力协同作用的结果.

Studies on the Self-assembled Behavior of Perylene Diimide-Chiral Surfactant Complex in Solutions

The complex N, ′-bis(2-(trimethylammonium)ethylene)-perylene-3,4,9,10-tetracarboxyldiimide-bis((3R)-3,7-dimethyloct-6-enyl)phosphate (PTCDI-BDP) was synthesized, and its self-assembly behaviours in ethanol/n-hexane and ethanol/n-octane binary solutions were studied in detail. It is believed that PTCDI-BDP molecules self-assemblied into nanotubes in ethanol/n-hexane and nanobelts in ethanol/n-octane could be ascribed to the cooperative actions including the π-π stacking, hydrophobic interactions and chirality.
