胡萝卜素是天然丰富的不饱和烃色素，其迷人的物理和化学性质已被深入研究，不仅是为了更好地了解其在生物过程中的作用，而且在人工化学系统中的应用。然而，它们的金属结合能力实际上尚未被探索。在这里，我们报道β-胡萝卜素具有组装和排列10个金属原子的能力，以提供十核同源和异金属链配合物。金属-类胡萝卜素框架与多种金属表现出可逆的金属-脱金属反应性，这使我们能够控制金属链的大小以及胡萝卜素支撑的金属链的杂双金属组成和排列。胡萝卜素是天然丰富的，广泛研究的不饱和烃色素，但其金属结合能力实际上尚未被探索。在这里，作者证明了它们可以用来可逆地组装和排列同源和杂金属十核链配合物。
Carotenes are naturally abundant unsaturated hydrocarbon pigments, and their fascinating physical and chemical properties have been studied intensively not only for better understanding of the roles in biological processes but also for the use in artificial chemical systems. However, their metal-binding ability has been virtually unexplored. Here we report that β-carotene has the ability to assemble and align ten metal atoms to afford decanuclear homo- and heterometal chain complexes. The metallo–carotenoid framework shows reversible metalation–demetalation reactivity with multiple metals, which allows us to control the size of metal chains as well as the heterobimetallic composition and arrangement of the carotene-supported metal chains. Carotenes are naturally abundant, widely studied unsaturated hydrocarbon pigments but their metal-binding ability has been virtually unexplored. Here, the authors demonstrate that they can be used to reversibly assemble and align homo- and hetero-metallic decanuclear chain complexes.
