摘要
设计合成了香豆素衍生物凝胶因子1,该凝胶因子可以在乙腈和N,N-二甲基亚砜(DMSO)中形成有机凝胶.通过紫外可见光谱(UV-vis)、红外光谱(FTIR)、扫描电镜(SEM)、X-射线粉末衍射(XRD)和接触角(CA)等技术对该凝胶因子在乙腈和N,N-二甲基亚砜的自组装过程进行了详细表征.该凝胶体系在氢键和范德华力的驱动力下自组装成微米带结构,该结构表面展示了疏水性质,其接触角为136.5°和124°.
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 °.
