The manipulation of carotenoid-based hierarchical superstructures affords attractive properties that facilitate application in biology and photosynthesis. Here, tubular suprastructures formed from water-soluble amide-modified resorcinarene and β-carotene were reported, whereas microsheets were formed when β-carotene was replaced with lutein. These structures were characterized using various measurements, indicating the differences of binding sites between resorcinarene and β-carotene/lutein. Subsequently, the assembly mechanism was described by calculating the formation energy of the assemblies.
类胡萝卜素分级超结构的操纵提供了有吸引力的性质，有利于在生物学和光合作用中的应用。在这里，报道了由水溶性酰胺修饰的苝和β-胡萝卜素形成的管状超结构，而当β-胡萝卜素被叶黄素取代时则形成了微片。这些结构使用各种测量方法进行了表征，表明了苝与β-胡萝卜素/叶黄素之间结合位点的差异。随后，通过计算组装体的形成能来描述组装机制。
