摘要：

A series of monocholesterol substituted quinacridone derivatives MCCn (n = 4, 6, 9) has been designed and synthesized. Compounds MCC6 and MCC8 can gelate a wide range of organic solvents upon ultrasound irradiation and afford intriguing well-defined nanostructures composed of three-dimensional sponge-like superstructures or Fibrous networks. Interestingly, the gel produced from MCC6 is sensitive to thermo-, aniline, and formic acid stimulus, giving obviously different aggregation behaviors as well as physical properties. Time-dependent spectroscopic data and theoretical calculation results provided explanation for the possible molecular aggregation mode during the formation of the gels.
