由手性苯-1，3，5-三甲酰胺1，2和3自组装形成了相互缠绕的手性三螺旋纳米纤维，而手性苯-1，3，5-三甲酰胺4自结合形成了没有任何扭曲的直线纳米纤维，手性化合物的透射电子显微镜图像清楚地表明，利用对映体苯-1，3，5-三甲酰胺构筑块可以反转三螺旋纳米纤维的手性。
Intertwining triple helical nanofibers with an overall handedness have been formed from self-assembling chiral benzene-1,3,5-tricarboxamides 1, 2 and 3, whereas the achiralbenzene-1,3,5-tricarboxamide 4 upon self-association gives rise to straight nanofibers without any twist and transmission electron microscopy images of chiral compounds clearly demonstrate that the handedness of the triple helical nanofibers can be reversed by using the enantiomeric benzene-1,3,5-tricarboxamide building blocks.
