| Abstract: | Coumarin derivative gelator1 was designed and synthesized, which could form organic gels in acetonitrile and dimethylsulfoxide(DMSO).The self-assembly process of1 in acetonitrile and DMSO was characterized by UVvis spectra, fourier transform infrared spectroscopy(FTIR), scanning electron microscope(SEM), X-ray diffraction(XRD) and contacting angle(CA).The gelator1 was 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 °. |
