Unusual gelation of a number of organic solvents by allyl cholate and other simple esters of cholic acid is reported. These gels were characterized by SEM, AFM, polarizing optical microscopy (POM), X-ray powder diffraction and other techniques. Electron micrographs of the xerogels revealed the presence of highly entangled 3D fibrillar networks. Direct imaging of the collapse of SAFINs and their thermal stability were performed using variable temperature polarizing optical microscopy (POM).
据报道，胆酸烯丙酯和其他简单胆酸酯可使多种有机溶剂发生异常凝胶化。这些凝胶通过扫描电子显微镜（SEM）、原子力显微镜（AFM）、偏光光学显微镜（POM）、X射线粉末衍射等技术进行了表征。干凝胶的电子显微照片显示存在高度缠结的三维纤维网络。使用可变温度偏光光学显微镜（POM）对溶剂辅助的纤维状纳米结构（SAFINs）的坍塌及其热稳定性进行了直接成像。
