Abstract: Coumarin derivative gelator 1 was designed and synthesized, which could form organic gels in acetonitrile and dimethylsulfoxide (DMSO).The self-assembly process of 1 in acetonitrile and DMSO was characterized by UV-vis spectra, fourier transform infrared spectroscopy (FTIR), scanning electron microscope (SEM), X-ray diffraction (XRD) and contacting angle (CA).The gelator1was self-assembled into microbelts structure under the driving force of hydrogen bonding and van der Waals force.The structure surface showed the hydrophobic properties, and the contact angle were 136.5 ° and 124 °.
